I could use 'libhid' to communicate with our USB based HID generic device.
'test_libhid.c' provided me a good starting point. Thanks Charles for
providing quick replies and support.

I need few clarification regarding the features provided my 'libhid':

 1) Is asynchronous non blocking I/0 operation supported by libhid-0.2.16. If
yes, can you please provide me its documentation?

 2)Can I simultaneously perform read and write operation at a time? Let me
elaborate. I will create a thread which will perform blocking
'hid_get_input_report'(libhid's equivalent read API) operation. In his
scenario, will 'hid_set_output_report' (libhid's equivalent write API)
request from another thread go through?

Thanks for the support.
