I already asked you to test if HID_QUIRK_NO_INIT_INPUT_REPORTS was
working for the same same kind of timeout
(https://patchwork.kernel.org/patch/3544281/).

So I am asking again: please test HID_QUIRK_NO_INIT_INPUT_REPORTS and
if it works, use this quirk instead the one in this patch.
This *really* matters because the quirk HID_QUIRK_NO_INIT_REPORTS does
not initialize feature reports which contains important information
regarding hid-multitouch.

Cheers,
Benjamin
