I got an ALPS touchpad with SPI interface and develop a simple driver to test on ThunderSoft Drop5.0. This touchpad could work in absolute mode and report absolute coordinate to input-subsystem, but it could not work in relative mode. I had switched it to relative mode and report relative coordinate to input-subsystem. Does anybody have any ideas? Thanks.
