Hi Benjamin,

This device is the worst device I saw. It keeps TipSwitch and InRange
at 1 for fingers that are not touching the panel.
The solution is to rely on the field ContactCount, which is accurate
as the correct information are packed at the begining of the frame.

Unfortunately, CountactCount is most of the time at the end of the report.
The solution is to pick it when we have the whole report in raw_event.

I think it would make more sense to introduce a method where the
driver sees all report values at once. We have had reasonable cause to
add it in the past, but never did.

I dreamed of this more than once in the early days of hid-multitouch, yes. But then it requires quite a few changes in hid-core.c, doesn't it?

Cheers,

St.
