I want to set up my embedded application as a HID device, with a separate process controlling the HID interface to allow dynamic connections to a PC. There seems to be many people out there that have done it, but I would like to do is:
a) Understand how to configure my build (Freescale i.MX Linux using ltib) to include the USB APIs and includes in my build (ie g_hid.h).
b) Where can I find an example application which does something like move the mouse about the screen to demonstrate the operation of the HID?
Thanx for your help!
http://lxr.linux.no/#linux+v3.3/Documentation/usb/gadget_hid.txt is an example of how to operate a mouse HID.
