ELAN0600 seems to work just fine in mouse emulation mode through i2c-hid, but to have full raw touch support we need to register it in elan_i2c.ko Reported-and-tested-by: Alessio Treglia <alessio@xxxxxxxxxx> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@xxxxxxxxxx> --- Hi, well, last discussion ended up that the patch was the right solution, so I am resending it now to get Jiri's ACK so Dmitry will be able to take it. Just for the sake of it, I double checked the Elan 0x0401 (a i2c-hid device which might be working with elan_i2c with some tweaks), which I have some debug logs, and I don't think we will be able to communicate and enable the raw reporting through HID. So sadly, yes, we need to blacklist in HID and enable in elan_i2c.
