In 3.9 and=20 3.10 it doesn't; the panel doesn't show up in /proc/bus/input/devices . If the module usbtouchscreen is present, 3.9/3.10 wrongly try to use=20 that one (flipped y-axis, wrong scale, get's stuck) instead of=20 hid-multitouch(worked previously perfectly well, no need for=20 calibration, quirks, configuration). If usbtouchscreen isn't present,=20 the panel isn't detected, even if hid-multitouch gets poked with approp= riate parameters in /sys/module/hid_multitouch/drivers/hid\:hid-multitouch/ne= w_id . In an desperate attempt, I manually added the device/vendor id to hid-multitouch.c, which didn't yield any improvement. It seems that the= hid subsystem doesn't even recognize that this device is indeed a hid=20 touchpanel. Is there a way to force hid to take care of that vendor/device-id, as a temporary workaround?
