david.chen and Anothy I think you should try the steps below: # modprobe hid-multitouch # echo "BUS 0408 3008 104" > /sys/module/hid_multitouch/drivers/hid\:hid-multitouch/new_id And you should replace BUS with the actual bus number of your device, if you are not sure what is, please post out the output of 'lsusb -vv'. If the above still doesn't work, please post output of 'dmesg' here, then I can see if the command has been run successfully. Thanks -- Ming Lei On Wed, Apr 11, 2012 at 10:07 AM, David Chen
