USB Host 2.0 connected to Arduino Mega 2560
A major revision of USB Host Shield for Arduino has been released and is available in the store. The board’s improved layout makes this shield compatible with more Arduinos, makes it easier to use and opens new possibilities. The main differences from rev.1xx are outlined below:
- The SPI interface has been moved to ICSP header making shield compatible out of the box with “big” Arduinos – Mega and 2560. Standard size boards, such as Duemilanove, UNO, as well as clones with classic connector layout, are also compatible with this revision of the shield. This compatibility is maintained on a software level as well – all necessary code changes are performed using conditional compilation preprocessor directives.
- USB connector has been moved to the opposite side of the board. All external connectors are now in the same place making enclosure layout easier.
- MAX3421E RESET line is no longer handled by dedicated Arduino pin. While MAX_RESET pin is still used in current version of USB Host library, it will be dropped from the next major revision of the code.
USB Host Shield 2.0 with AVR Dragon
Besides “Mega-formfactor” compatibility, connecting to Arduino SPI signals on ICSP connector has several advantages. First of all, in this layout traces are much shorter and as a result, the shield works more reliably at higher SPI speeds and/or larger signal and power noise. Second, since the 2X3 connector, which comes bundled with the shield, is of ‘stackable’ variety, it is possible to connect AVR Dragon or other ICSP programmer to Arduino while USB Host Shield is mounted – picture on the left shows the arrangement. Finally, pins 11-13, occupied by SPI signals on “classic” Arduinos, are vacant on Megas and also uncommitted on the shield. Therefore, they can be used for other purposes without USB library code modifications.
The shield comes in 2 configurations. One, called “Standard” is compatible with official full-size Arduino boards (Duemilanove, UNO, Mega, Mega 2560, and possibly others), as well as clones which supply both 3.3V and 5V to the shield. One example of such clone is BlackWidow; if you are aware about other compatible clones, please let me know.
Another configuration, called “3.3V” is designed for battery-operated projects. It is compatible with Sparkfun’s Arduino Pro 3.3V board (I’m not aware of any other 3.3V-only full-size clones). It also supplies 3.3V to VBUS instead of spec’d 5V, therefore some bus-powered devices may function erratically (but not necessarily; I actually use bus-powered USB flash drive during final testing of production 3.3V shields). Self-powered devices, such as digital cameras, usually don’t care about VBUS voltage at all. Additionally, board layout makes it possible to mount external power supplies to generate 5V from 3.3V and vice versa, if necessary.
The shield is compatible with current version of USB library. It is also very similar to rev.1.xx shield and information from previously posted articles is mostly valid for 2.0 board. Schematic and Eagle CAD files are also available for download. I am currently working on detailed description of the shield and hoping to get it ready in a week or two.
Along with this shield I will continue producing rev.1.21 board – there are still “not-so-compatible” Arduino clones around. However, next major revision of USB library will not be compatible with rev.1xx shields; it will be possible to make it work after minor hardware/software modifications.
As always, your questions and comments about the product are welcome and appreciated.

Hello Oleg,
does the statement “next major revision of USB library will not be compatible with rev.1xx shields” affect the mini shield as well?
Currently shipping minis won’t be affected. For older shields, just a minor modification will be necessary.
Hello Oleg,
Is the minor hardware modification applicable to SparkFun Electronics’s USB Host shields (DEV-09947 and DEV-09628)?
Hello Oleg,
I’m trying to use a USB trackpad (Bamboo Touch) with your USB Host Shield (rev 1.21), but there is a type 5 Mouse polling error when I try to connect. Is this because the device is not recognized? If so, do you know how to mitigate this?
Thanks,
5 is Stall; the device doesn’t support your request. Can you show your device’s descriptors? Also, which sketch are you using?
Hello,
I couldn’t tell you which descriptors it’s using; there’s no mention of this device in the USB HID files. As for the sketch, it’s the “/* Mouse communication via control endpoint */” sketch (the first example on http://www.circuitsathome.com/communicating-arduino-with-hid-devices-part-1)
Is it possible to write a unique descriptor for this device? http://www.wacom.com/bamboo/bamboo_touch.php
Thank you for your prompt response,
Run descriptor parser -> https://github.com/felis/USB_Host_Shield/tree/master/examples/descriptor_parser and see if you can get meaningful output. You’d need to see report descriptor for your mouse anyway.
Hello,
Update: I got a response when I used your
/* Mouse communication via interrupt endpoint */ /* Assumes EP1 as interrupt IN ep */
code (the second in the above link); sorry for not checking sooner.
Hello Oleg,
Currently, I’m able to run both a USB mouse and USB trackpad, but only in separate sketches.
When using the control endpoint method, the mouse works but the trackpad returns a type 5 error (stall)
When using the interrupt endpoint method, the trackpad workds, but the mouse returns a type 5 error
It’s unusual that the device doesn’t support the request in one sketch but not the other…
I looked at the device descriptors, and both devices are recognized:

Any ideas? Thanks again for your help thus far. It’s much appreciated.
The trackpad has several reports and consequently several report IDs in HID report while mouse has only one report and therefore doesn’t use report IDs. When polling via control endpoint, you need to either specify report ID which you are requesting, or use “0″ for report ID parameter when no report IDs are used. That’s why sketch works for mouse and doesn’t work for the trackpad – you need change report ID 0 to an actual report ID in “rcode = Usb.getReport( DEVADDR, 0, 4, 0, 1, 0, buf );” function call.
When polling interrupt endpoint, you can’t specify report ID and are simply getting whatever reports are available at the moment. That’s why interrupt polling works with trackpad. I’m yet to find out why it’s not working with a mouse – I’ll keep looking.
Hello again,
I’ve been playing with the host shield (rev1.21) a bit more, and have been having issues running certain mice but not others. I’ve tried with 5 or so different models of mice, and have only had luck with 1. The only remarkable difference is that the HID version for the mouse that works is 1.10, while that of the mice that don’t work is either 1.0 or 1.11. The data packet size is 8 for all these mice, and the USB version is either 2.0 or 1.10.
I’ve been using the control endpoint sketch, because as I mentioned, I’m unable to get mice working with the interrupt endpoint method. All the report descriptors for these mice are quite similar; the error involved is usually a stall. In the case of wireless USB mice, the serial monitor crashes entirely after returning many stall errors.
Do you have any idea how the HID version could influence the workings of different mice? Also, are extra drivers required to support wireless USB mice?
Thanks,
By USB spec, HID mouse must answer on interrupt endpoint. Can you send me your whole sketch – I’d like to take a look?

As I mentioned, the interrupt endpoint method doesn’t work with any USB mouse. The error is usually:
Start
Data Packet Error: 5Get Idle Error. Return code: 5
OR
Setup Packet Error: DError configuring mouse. Return Code: D
D means “JERR” which I haven’t been able to figure out.
In interrupt sketch, change EP_MAXPKTSIZE from 5 to 4 and see if your mouse starts working
Hello,
I’d tried that previously with no luck. If I change EP_MAXPKTSIZE from 5 to 4 in the interrupt sketch:
For the mouse with HID Version 1.10:
Start
Data packet error: 5Get Idle error. Return code : 5
For the mouse with HID Version 1.0:
Start
Setup packet error: DError configuring mouse. Return code : D
Also,
Are you getting
Start
Idle Rate: 0 ms
when you start interrupt sketch?
I think I found the issue. Microsoft mouse returns Stall to GetIdle/SetIdle commands. The sketch stops on any error. Do this: find all
while(1); //stoplines (should be 3, on line 60, 66 and 76 in interrupt sketch listing on this page -> http://www.circuitsathome.com/communicating-arduino-with-hid-devices-part-1 ) and comment them out. You will still be getting errors but sketch will continue and eventually you will see this:Start
Data packet error: 5Get Idle error. Return code : 5
Idle Rate: 512 ms
Set Idle error. Return code : 5
Button1 pressed
X-axis: 0
Y-axis: -1
Wheel: 2
Button1 pressed
X-axis: 0
Y-axis: -1
Wheel: 0
Button1 pressed
X-axis: 0
Y-axis: -1
Wheel: 3
You will need to move your mouse to see reports.
Let me know if this helped.
This is odd – I’ve tested many different mice and none of them behaved like yours. Can you give me make/models of your mice and where you got them – I’ll try to source one locally and check on my system?
Hello,
Commenting out the while(1) did the trick. I’m now able to read every mouse, and the trackpad, all from the interrupt endpoint sketch! Thank you very much for your assistance, Oleg. You’ve helped paved the way forward.
Here are the models I have been testing with:
o RocketFish Nano Laptop Optical Mouse (wireless USB)
o Logitech M570 Trackball Mouse (wireless USB)
o Microsoft IntelliMouse Optical USB and PS/2 Compatible (Wired)
o Microsoft Ready Mouse (Basic Optical, Wired)
o Microsoft Wheel Mouse Optical 1.1A USB and PS/2 Compatible (Wired)
The wired mice buttons are all interpreted the same way (left click is button 1, right click is button 2) but the wireless mouse has a different mapping of inputs (button 1 corresponds to one of the optical sensors instead). I’ll probably build a condition into my final sketch to identify the device and act accordingly.
Interestingly, the Logitech wireless trackball I mentioned above gives no response to the interrupt method, nor is it detected in the control endpoint sketch. Here is the response:
Start
Idle Rate: 500 ms
… nothing happens after this point. Clicking, re-starting, re-plugging in the dongle, etc. has not worked.
I have increased the max packet size to both 8 and 0020 (0008 will not compile) to try and accommodate a larger bandwith, but that hasn’t worked.

Just food for thought, I suppose.
Lastly, I’ll be porting your Simple USB Shield design onto a new layout within a week or so. We’ve identified the necessary components for its operation, and plan to incorporate your design into a larger PCB to acommodate binary switch inputs and the like. Would you be alright with reviewing our changes and providing your input? My team and I would be very appreciative of your expertise.
Thank you once again for your help thus far.
I can’t see what is wrong with wireless trackball.
If you need help with your commercial project, I am available for hire. Contact me off-list for rates.
I have connected a mouse to the USB Host shield and when I run the code from http://www.circuitsathome.com/communicating-arduino-with-hid-devices-part-1 I get the error
Mouse poll 4.
Any idea why it is happening and any way to fix it?
There are two sketches on this page – which one you are referring to? Have you tried to move your mouse at all? 4 means NAK, it happens when no new data is available. Also, which shield variant are you using?
I am using the first sketch that was present in that page. Yes I tried moving the mouse and also tried clicking the buttons, but I kept on getting the same error.
I am using the USB Host shield from Sparkfun with has the pins swapped. http://www.sparkfun.com/products/9628
But I have made the following changes before proceeding.
#define MAX_GPX 7
#define MAX_RESET 8
Okay I found an interesting thing happening. If I don’t mouse the error, then I am getting the error Mouse Poll error: 4, which you explained as NAK.
But when I try to move the mouse or click a button, I get a different error. The new error is “Data package error: E followed by Mouse Poll Error E”.
I’m not familiar with Sparkfun shield but I heard there are power issues – you may want to read comments on their product page.
Hello Oleg
Following your suggestion and forgetting Ligthweigth_USB for PIC, I’m trying to take the logic of this code and the MicroBridge application that is written in C.
My goal is to read pendrive. When trying to run the sequence GET_MAX_LUN, UNITY_READY, SENSE_INFO, READ_CAPACITY and INQUIRE to establish the Mass Storage Device the error 0x0D appears in the first step.
This error and much talked about in various forums and no solution is available.
The first step GET_MAX_LUN for Mass Storage Device Class, I inserted into the case (USB_STATE_CONFIGURING).
Is it possible for you to indicate someone or some place that has treated the Mass Storage Device with this library for MAX3421.
Thanks
JGomes
You can’t issue mass storage commands before device is configured. Error 0x0d happens when device doesn’t understand what’s being sent to it and caused by either incorrect data or bad power. The solution is to program correctly and make sure adequate power is provided to VBUS.
I saw some mass storage code for my shield posted on old Arduino forum. Microchip also has mass storage code in its’ USB stack – it is not really controller-specific.
Are the extra row of pin holes along the digital and analog pin rows already connected to the main row, to use as pass-throughs for the unused digital/analog pins from the Arduino below?
Ahhh, nevermind – on closer inspection I can see the trace connection each row to the secondary row. Just didn’t want to start soldering where it wasn’t needed!
Yes, they are. There is more information about shield hardware here -> http://www.circuitsathome.com/usb-host-shield-hardware-manual
Hallo Oleg,
I am trying to make a USB mail notifier work using your USB host shield.
http://www.dreamcheeky.com/webmail-notifier
It seems straight forward but somehow i can not get it to work.
I need to send report ID 00 to the unit to innitiate it and to get it to change its RGB led.
The innitiation codes are:
msg1[7] = { 0x1F, 0×01, 0×25, 0×00, 0xC4, 0×00, 0×25, 0×03 };
msg2[7] = { 0×00, 0×01, 0×25, 0×00, 0xC4, 0×00, 0×25, 0×04 };
Then you send the colour code eg:
msg3[7] = { 0xFF, 0xFF, 0×00, 0×00, 0×00, 0×00, 0×25, 0×05 };
The first three bytes are the brightness and colour coding. RR GG BB. I think it has 0x3F brightness as higher values do not increase the brightness.
How do you send this data to the unit. I have tried outTransfer but am not sure how to use.
I know the USB host works because i can read the RFID codes from the Violet Mirror RFID device.
I know the mail notifier works because i can switch it using simpleHIDWrite from http://www.lvr.com/hidpage.htm
To write to HID device you either need an OUT endpoint or write to control endpoint. If your HID device has OUT endpoint (not typical), just do an outTransfer to it. In any case, you should be able to write to control endpoint; here is an example -> http://www.circuitsathome.com/mcu/how-to-drive-usb-keyboard-from-arduino , look how I turn keyboard LEDs on/off – you should be able to do something similar on your device.
Thank you Oleg,
Its now working and here is the code. Its just a simple program to light up the RGB LED in the different basic colours.
As you can see i did use the setReport function as you had done in the keyboard example.
Now to find something usefull to do with it.
I still dont understand anything about USB though. eg why does the setConf require the 0x1F conf_value and still require the initiation sequence to be sent.
Anyhow if it works maybe it does not matter.

Glad it worked for you. Are you going to post your project somewhere? If so, could you please send me a link?
Oleg,
I just got my usb-shield and am enjoying learning how it works. My goal is to get it to talk to an ST/Ericcson GSM modem I have using simple AT commands. I see many others on the web trying to do the same thing. I’ve seen several example arduino codes that you and others have written to do all sorts of fancy stuff via USB.. What I haven’t found is a simple ‘hello world’ example on how to use the usb-host shield to issue simple string commands (eg. ‘AT…’) and retrieve the responses from soemthing like a modem. Do you or anyone else here have such an example ? Thanks so much !
-jc
This will be supported in the next revision of USB Host library.
I’ve just got the Sparkfun-branded USB host shield (silkscreen date 5-28-10) and I was looking at the MAX3421E datasheet. It can act as a USB host, which is why I wanted the shield in the first place, but it also supports acting as a USB peripheral. So now I’m thinking that this would be a good way to get my Arduino to imitate a real USB HID device of its own.
As an example, using the 12Mbps high-speed interface to dump ADC data into a PC’s Notepad application faster than it can be transferred through the FTDI COM port.
Obviously, the Arduino would have to be programmed differently to set the 3421 to act as a peripheral rather than a host, and the various USB identifiers would have to be set, etc
But the real question is one of hardware: is there an easy way to add a mini- or micro-USB jack to the board? I assume it’s just a matter of tapping into the same VBus, D-, D+, and GND that’s on the USB-A jack and adding a USB-B jack, but will that mess up the signals and/or voltage elsewhere?
–Joe
And as you can with your USB Host Schild recorded on Flash drive a text file?
Mass Storage code is not ready yet.
If I plugged in two ps3 controllers into a usb bus and then into the USB Host Shield 2.0 that was connected to an arduino, would the arduino identify and recognize that button presses are coming from two different controllers or would it assume that button presses from any of the buttons on the two controllers are coming from a single controller input?
I meant usb hub instead of “usb bus”
For each device you’d have to declare an instance of the device object. If your devices are the same you’ll declare two instances of the same device. At the end, you will know what data comes from which instance.
Note, however, that PS3 controllers are not yet supported in rev.2.0 of the library.
Ok about the device declare. I didn’t know that rev.2.0 doesn’t support PS3. Do you know when it will be? Just to clarify the legacy usb host shield for arduino currently supports PS3 controllers, correct?
PS3 is supported by Richard Ibbotson’s code -> https://github.com/ribbotson/USB-Host I’m just hosting the articles.
Please bear with me as I am not an expert in electronics. Yes I have seen Richard Ibbotson’s code and I realize you are just hosting his articles. My question is which specific arduino usb shield (that you sell) do need to use with Richard Ibbotson’s ps3 library code so that I can read button presses from a ps3 controller? The arduino I will be using is an Arduino Duemilanove.
you need full-size shield, var.standard -> http://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-2-0-for-arduino/ It is compatible with Richard’s code (and any other legacy code, too).
Thank you very much for your help and your quick replies. You have been very helpful.
I Have little bit error when i try compile the code,
I get error : bt_h.h:104: error: ‘EP_RECORD’ does not name a type. How to fix it.
Thankyou…
Regards
Welly
For bluetooth code use legacy library.
If I stack a shield that uses standard SPI pins 11-13 on top of the USB 2.0 shield, which is on a Duemilanove/Uno, it will work as long as the other shield does not use pin 10 for SS, right?
In general, yes. However, some shields/chips won’t switch MISO line into high-Z state while not selected – this may cause issues.
The shield that I’m using is the Adafruit data logging shield.
I’m posting to report that it works fine with the USB Host shield 2.0, logging GPS data from a Pharos GPS-500.
Hi,
I wonder whether there is a way to reset and initialize the Usb shield and the library (legacy version) by software.
(Sometimes, the library and arduino crashes while reading data from USB, i could probably solve the problem by reset everything after certain actions)
Thanks!
You can jump to address 0 – this is equivalent to pressing RESET button. Look how this is done here -> /mcu/bluetooth-code-for-arduino-usb-host
Hello, Any luck with mass storage code/communication?
Thanks in advance.
Hello Oleg,
I would ask how to make any usb peripheral i.e. USB to Ethernet adapter or any GPRS usb modem work to USB host shield 2.0?
Use examples from the library or write your own code.
Thank you for reply Oleg.
What example should I use as base code to make USB to Ethernet converter work to usb host shield?
Is is pl2303 terminal?
Thank you.
If your adapter is CDC Ethernet type, ACM would be better. Pl2303 is close too.
Hello Oleg,
You have a very nice and understandable page.
I hope this is the right position for tis post.
For a student project, I took your code / * Mouse control via communication endpoint * / from the http://www.circuitsathome.com/communicating-arduino-with-hid-devices-part-1 page.
I have problems with the code of the current libary from the following page: https://github.com/felis/USB_Host_Shield
my problem is the difference between the library from your Projet state to the current library state.
Could you tell me the name of the appropriate library or a complete package with a sample program?
Thank you for your efforts
Hello Martin,
The new library is here _. https://github.com/felis/USB_Host_Shield_2.0 , the mouse example for it is here -> https://www.circuitsathome.com/mcu/hid-support-for-usb-host-shield-library-2-0-released
Hello Oleg,
Thank you for your fast response.
My specific problem is the cyclical polling of the mouse.
The “boot protocol” is not possible in my application,
because in your code the Arduino “loop()” stops vor 5 seconds if the mouse does not provide new signals.
How could I change this code (boot protocol)?
Thank you.

You’re trying to use legacy example with new library. This will not work.
Hi Oleg,
and how can I modify the code to my requirements?
which library should I use for this example?
I use the Arduino software 1.0 and your host shield.
Thank you.
the library is here-> https://github.com/felis/USB_Host_Shield_2.0
Hi Oleg,
yes this is the link to the Library “71dcc7e534″
But this is not kompatibelmit with the program line:
44 Usb.setEpInfoEntry (1, Usb.getEpInfoEntry (0,0));
from your legacy example / * Mouse control via communication endpoint * /
I neet the old Library or a modify code which is running on the
Arduino 1.0 software.
Thank you.
Here is a dilemma: the legacy library is here -> https://github.com/felis/USB_Host_Shield but it won’t compile in 1.0; you’d have to replace all occurrences of
WProgram.htoArduino.h. Look how this is done in the new lib, for example, here -> https://github.com/felis/USB_Host_Shield_2.0/blob/master/Usb.h#L37Hi Oleg!
I want to read the MIDI code from the Akai MPD18. I would use the Code from Collin (www.circuitsathome.com/mcu/interfacing-midi-devices-with-arduino-using-usb-host-shield), but I don’t know how to read the definitions out of the descriptor_parser.

Please help me!
Hi – I’m enjoying the USB shield with a bluetooth dongle, works great every time.
My only issue is trying to send some floating point numbers, from a self-balancing robot experiment, back to a processing gui to display sensors and motor outputs and also adjust the PID loop – BT is nice as I won’t have a usb cable pulling the robot off balance
However, the SerialBT.print does not appear to support float like the normal Serial.print – and everyone else suggests using dtostrf() which looks like a real pain
Any other suggestions?
Thanks for a great board, the supporting libraries are fantastic.
I’m not familiar with float representation in avrgcc, but this is how I would fix this: learn how float is allocated in memory then cast your variable to whatever integer fits this allocation then transmit the integer then cast back to float.
Hi Chuck,
I’m planning to add this routine: https://github.com/TKJElectronics/BalancingRobotArduino/blob/master/BalancingRobotArduino.ino#L296-L326 to the SPP library in the holiday coming up, then you will be able to print floating numbers using printNumber(). For now just use the function I wrote.
See the latest commit I just pushed to github: https://github.com/felis/USB_Host_Shield_2.0/commit/a4f21cea8cd68a2c7c8cd7570a50f9823456bff9
Now you can simply print a floating-point number using “printNumber()”.

I am not sure which report descriptor parameters to plug into the getreport method. I used usb.getReport(DEVADDR,0,20,0,1,0,buf) Does that look right?
Why not just use the library I wrote: http://www.circuitsathome.com/mcu/xbox360-controller-support-added-to-usb-host-shield-2-0-library?
I don’t see a way to download that library. Can you put up a link that directs me to an actual download.
I actually wanted to adapt the mouse program to read the xbox reports so that I understood better how it works. It seems, you simply need to know the endpoint and report you want, or just set ep to zero to get any report that updates. But I cant tell from the descriptor above which report parameters to use. I should be able to simply serial.print the actual hex string to my serial monitor when an event occurs. Then I can watch it for changes when I press buttons or whatever, it’s more of a learning exercise.
Ok, I got it to sort of work. Following is the part of the code I think is wrong. I do get a response when I press the buttons, but I believe I am not reading the correct buf memory bytes in the “if( buf[ 2 ] & 0×00 )” statements. Is there a section that shows the report’s bit mapping for the different inputs?
rcode = Usb.getReport( DEVADDR, 0, 20, 0, 1, 0, buf );
if( rcode ) { //error
return( rcode );
}
for( i = 0; i < 20; i++) { //check for new information
if( buf[ i ] != old_buf[ i ] ) { //new info in buffer
break;
}
}
if( i == 20 ) {
return( 0 ); //all bytes are the same
}
/* print buffer */
if( buf[ 2 ] & 0×00 ) {
Serial.print("Dup pressed ");
}
if( buf[ 2 ] & 0×01 ) {
Serial.print("Ddn pressed ");

The code is available at github.
Here is a link to the example sketch: https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/XBOX360USB/XBOX360USB.ino and here is the link to the source code: https://github.com/felis/USB_Host_Shield_2.0/blob/master/XBOXUSB.cpp
You can find an explanation of the report at the following link: http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/UsbInfo
OK, so I got thru that successfully and have moved on to trying out the Open Accessory mode on an HTC Droid Incredible. It shows SW version 2.3.4 so it should be compatible with the ADK libraries.
Vendor ID: 0BB4
Product ID: 0C9E
I dont’t believe the Vendor ID and Product ID are compatible though…how do I make this phone work with my Arduino Mega ADK USB Host thru Open Accessory mode?
See this example: https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/adk/ArduinoBlinkLED/ArduinoBlinkLED.ino
The source code for the Android app can be found here: https://github.com/Lauszus/ArduinoBlinkLED
Hope this will get you started.
So, I have the Mega ADK Board. So, I need the USB ver.2 correct? I would have to adapt your sample code to use USB ver.2?
Just uncomment this line: https://github.com/felis/USB_Host_Shield_2.0/blob/master/avrpins.h#L25 and it will work just as you were using the shield.
Where would I find error codes for values returned from a HID SetReport()? I getting “D” hex back as the response.
This is a result code of a transaction. Please take a look at the MAX321E Programmer’s Guide -> http://pdfserv.maximintegrated.com/en/an/AN3785.pdf
Hello Oleg,
I’ve just purchase USB Host Shield v2.0
because I want to interface 3G USB Modem (Huawei E303 Cloud+ OR Huawei MF 1805) to my Arduino Mega
I think both of them don’t have pl2303 !!
What example should I use as base code to make it work with usb host shield?
Is is pl2303 terminal?
if not could you guide me, how can I make it work ?
Thanks
