I took another look at it and would appreciate a little more advice.
First off, it seems that regardless of which flags I use (except for
ALPS_PASS), the first byte is 0xff for all packets. So those masks
don't seem to do anything useful for my device.
The touchpad does work fine. And with ALPS_DUALPOINT, packet[5] always
comes out as 127. However those 4 bytes in the middle act a little
weird. It looks to me like they are just rotating as if the packet size
is incorrect.
[ 1325.709029] alps packet: ff 02 00 00 08 7f
[ 1325.722834] alps packet: ff 00 08 02 02 7f
[ 1325.737028] alps packet: ff 08 02 00 00 7f
[ 1325.760152] alps packet: ff 01 00 00 08 7f
[ 1325.773963] alps packet: ff 00 08 01 00 7f
[ 1325.824228] alps packet: ff 00 01 00 08 7f
[ 1325.838144] alps packet: ff 01 08 00 00 7f
Where do the first and last bytes come from? Are they being sent by the
device, or added by a driver?
Any thoughts?
