The mouse data packets will have a different device address (data[0]>>4) & 0xf, so you can filter on that for debugging purpose (the adbhid input routine returns if the device address isn't registered as a keyboard anyway). The question is are there any _keyboard_ packets from register > 0 or length !=3. Michael
