Dolabra took up the task to add support for the HID class to Hoken and JTR’s open source USB stack. Up till now it only supported the CDC class, and HID is still a long way away, but progress has been made.
Yeah! a small victory. I got a set of descriptors that enumerate! The biggest problem that I had is that the HID driver sends a GET_DESCRIPTOR request as at standard request to the interface. The stack isn’t really set up for that and it took me quite awhile to figure out that is what was going on.
If you’d like to help out in designing a true open source USB stack, head to the forum.
