SubjectRe: [PATCH 20/20] HID: hid-multitouch: Add missing contact count detection
Hi Benjamin,

This is really terrible :-) Ok, so let's set maxcontacts to 60 on the
3M class, that ought to work for all present devices, right?

> And of course, 3M decided to stop sending 60 touches on their recent

Odd indeed. Speaking of oddness, I have two patches for the Flatfrog
MT 3200, which 1) Uses more then 128 fields in the report descriptor
(ever seen that before?), and 2) Advertises axes that are not
used. But it does give 40 touches worth of awesomeness once quirked
properly. Will send shortly.

Thanks,
Henrik
