Thanks Jiri.
How about patches 2,3 and 5?
Patch 2 is waited for LG users since a long time now (though it gives warnings).
Patch 3 can be included without patch 4: just loading hid-multitouch
makes the device working. And even if it's a little "hackish", it
won't hurt any other hid devices.
Patch 5 will introduce more robustness for the default class, but
requires patch 3.

Cheers,
Benjamin
