Sorry I made another mistake. hid_rmi is specifically for the Synaptics
RMI4 touchpads. We use let hid_elan handle this device. The
vendor&product id should be added to elan_devices in drivers/hid/hid-
elan.c. Can you give the following patch a try?
diff --git a/drivers/hid/hid-elan.c b/drivers/hid/hid-elan.c
