Hello,
I have been an avid windows user and used APIs to interact with the USB HID
device using hid.dll (DllImport("hid.dll",...) and all those stuff.I get
easy access to functions like _SetoutPut and _GetInput Report and can send
custom messages to HID USB device.(HID Compliant Device in the device
Manager).
Now I want to achieve the same with the libusb on Linux(and later On
Android).I looked into the code and found HID related code inside xusb.c
files.
I wanted to know is it possible to :
read HID Input reports(sync and Async both) and send Custom HID messages in
the HID Output report and get the response HID GetInput Report using libusb?
I see there is /jni bindings for android but can I achieve getting/sending
input/output reports using this.
I know my HID USB device and can create OUT Reports to it.
please advice the pointers in the code if it is possible.
Thanks in advance
Rgds

For Linux, please look at HIDAPI, I think it will be easier for you
than using libusb.
Ref: http://www.signal11.us/oss/hidapi/
For Android, I do not know how well HIDAPI works under
Android, libusb is not that good under Android right now
unless you have a rooted device.

Thanks for the reply.
Is the rooted device only issue with libusb or Android.I have seen port for
libusb on Android using ndk on github.
I am looking for below two option :
(1) Port HIDAPI you mentioned above to Android if it is possible with no
dependency on Android.HIDAPI uses libudev which I think is not available on
Android?
(2) Use Libusb on Android whose port is available on git and use it in
application.
My device is not a bulk transfer device rather an HID device to which
output report is to be sent which I am able to do with the HIDAPI but not
sure if it is portable to Android.

Hopefully others can help you better. Or maybe you should forget about HIDAPI and libusb under Android and use the native USB API of Android. -- Xiaofan |

native USB API of Android. >> Need to check it out.Btw there is UsbManager class in java which has the .controltransfer and .bulktransfer routine.Any way goign in the direction of .controltransfer right now as the parameter it takes looks similiar to that of one sending output report. what is the driving force to program in C on Android when the platform so clearly is Java 'only'... >>Elaborate.C gives the power to do anything at the native layer.Sometime java APIS dont give that much power.Ofcourse the device needs to be rooted. Looking forwards for more comments on HID Apis for Android.

Android is not at all Java only - the NDK is proof of this. Often people have a large body of existing code they want to re-use on Android, or share between Android and other platforms that their application supports (MSWin, OS X, Linux, iOS, etc.), and C and C++ code is the common denominator. Cross platform UI kits like Qt use the NDK to make their cross platformness possible. You certainly don't want to have to maintain a large amount of the same code written in both Java and C/C++ - what an error-prone waste of development time that would be! Graeme Gill. |

I haven’t had time to look at this code, but how I’m going to handle it right now is have the android code open the device, and either call the java library from C, or register a callback for the control transfer in my c-lib. That way, I don’t have to maintain a copy of my code in java. Would love to see built in android support.

OK Here is the good news and the Bad News : I successfully ported the hidtest.cpp for android using libusb (not hid-raw).I modified it for my device for sending output reports.I tested the code with my HID device on Android and I am able to communicate with it . But the bad news is Only SendOutput report works.The input response which I am supposed to get for the corresponding output report is still null.Anyone knows about this or is it a known issue.

Both should work if you just need to get a few input reports. For continuous reading of the input reports, you should use libusb_interrupt_transfer.

Do you have access to the communication protocol or the firmware of the device? Since you have access to a USB analyzer, you can sniff the communication protocol with the working Windows program (using hid.dll) and compare the behavior. -- Xiaofan |
