It is hard to say what is wrong. I would start with reading the uhid / hid code and see where you are getting stuck (and double check uhid docs). Even for others we would need to do that as it is not easy to see what is wrong. I'm not sure what your goal is obvious you want to simulate a keyboard for some purpose, but do you really need to operate at the HID layer? If not it is much more convenient to use uinput, which will create a evdev device for you.
