This is with a single finger stadily on the touchpad. X/Y/Z all seem to
move a bit around.
I added a few debug printks to alps.c and see that it correctly gets
detected as a rushmore/v3:
ALPS touchpad: E7=73 03 0a, EC=88 08 1d
alps_identify detected proto 3
This is the data sequence it generates:
alps decode af 46 2c 08 35 1b
alps decode 9f 46 2c 08 31 1b
alps decode 8f 46 2c 08 33 1b
alps decode 8f 46 2c 08 32 1b
alps decode 8f 46 2c 08 32 1b

alps decode 9f 46 2c 08 38 1b
alps decode 9f 46 2c 08 32 1b
alps decode 9f 46 2c 08 35 1c
alps decode af 46 2c 08 37 1b
Is this expected behaviour? From a quick look at alps_decode_pinnacle()
it looks sensible. Anything I can do to debug it further?
