this is the Peter Barrett USBHostShell program, a bit modified for being a bit more talkactive, just to let u know how the USB protocol layer is going on, and all the data trasnfers. Also there is a small implementation of HID descriptors, but not functional... yet :S the aim is to at least implement the gamepad HID, and make an array of function pointer to each HID function
