Could you please test the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS instead?
The patch is perfectly fine, but usually when it fails, only the input
reports are non-readable, whereas features should. This way, you will
still get the value of the features, which _may_ be sensible for the
maxcontact information.
BTW, HID_QUIRK_NO_INIT_INPUT_REPORTS has been introduced in v3.12 and
is the default for Win 8 certified devices.
Cheers,
Benjamin
