Did you have uhid(4) in the kernel or loaded as module? If not, please try= =20 loading the module and see if the device gets picked up by it (you need to= =20 replug it after loading the module). Judging from the description of the protocol, it seems that the device is a= =20 regular USB HID device. If it doesn't get picked up by uhid(4), it suffers= =20 from the same problem as the gamepad of the Xbox360 by not exposing itself = as=20 being a regular USB HID device and not providing a HID descriptor. Both can= =20 be worked around but please verify first, that uhid(4) doesn't already=20 support the device. Writing an extra driver for this device is not=20 neccessary.
