These two patches finally enable the kernel to handle multitouch devices correctly.
If a device presents in its report descriptors the usage Contact ID, then it is considered as
a multitouch device and handled by hid-multitouch.

Hi Banjamin,

thanks a lot for working on this. I have now queued the patches in my 
tree.

Hi Benjamin,

Late as it seems, here are a couple of questions:

1. How was this tested? By removing all white-listed devices in
hid-multitouch.c to see if the usual suspects are still picked up?

If we didn't have full test coverage (which I suppose to be the case), we 
can still revert to the old method after the merge window if there reports 
that this broke things on particular devices.

Do you guys at least have report descriptor dumps from most of the 
supported devices?

Yes, we have report descriptors for about 20-30 different models now, and about 10 actual devices for testing purposes. Unfortunately, this still does not tell us exactly how all these devices manage to work with the same Win 7 driver, given their diversity. We are getting close, but just not yet.

BTW we gladly accept to receive sample panels from vendors, this usually ensures fast support. Additionally, the panels are then reused by ENAC students in their projects, so this stimulates the market of multitouch devices in aviation :-)

Cheers,

St.
