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?

Well, nearly all the devices that has been included since March passed
the first patch (I had it in my queue since a long time).
For now, only Stantum products are known to not work with this patch
if we remove them from hid_have_special_driver.

I see, thanks.

As for the blacklist problem, we also know that this is not very
beautiful, but we are working on a better solution. For the moment, it
just allows people to have their device working out of the box
(crossing fingers).

It is great that you share a working solution for most cases, but it
does not look like mainline material yet, does it. A clean solution
should probably modify the driver selection mechanism on a deeper
level, or at least make use of the current whitelist.

Thanks,
Henrik
