ISDv4 and v5 are plain HID devices. We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Jason Gerecke <killertofu@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
