The wiimote uses a fake HID protocol. Hence, we need to prevent HIDINPUT and HIDDEV from parsing wiimote data and instead parse raw hid events. Add VID/PID to hid-core so the special driver is loaded on new wiimotes. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
