    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
