Hello Everyone, I am not too sure whether I am posting to the correct forum, but here is my problem. I have a USB HID device which I want the XO to be able to talk to.(Basic "recognize HID device","read", "write" etc). I have a windows dll which talks to the HID. I have the source code of this dll. I had thought that it would be easy to build a .so using the source code. But it is not so. The source accesses window specific headers like hidsdi.h and setupapi.h. My question is, are there equivalent linux headers for hidsdi.h and setupapi.h which have similar functions so that I wouldn't have to make major changes in my source code? If you have a USB HID device(apart from a mouse or keyboard) and you can identify it, read from it and write to it in Linux,can you let me know how you did it? Thanks! Ankita
