Issues with hid-multitouch driver

Hi guys,

I'm having issues with the hid-multitouch driver in kernel 3.14.
I have the following touchscreen device:

Bus 001 Device 003: ID 03fc:05d8 Elitegroup Computer Systems

The thing is that the driver detects the device correctly and even
works seemingly OK, until you start doing multi-touch taps on the
screen.

At some point, the input to the Xorg server stops.

I investigated this further, and using evtest, I can see that the events
ABS_X and ABS_Y stop being generated, and also that BTN_TOUCH event
gets a "value 1" for the touch before the freeze, but it is never
released: no "value 0" for the touch release event, ever.

After the driver gets braindamaged, it only generates
ABS_MT_POSITION_Y, ABS_MT_POSITION_X and ABS_MT_TRACKING_ID events,
and therefore no further clicks or normal Xorg pointer movement
on-screen.

I even tried backporting the lastest version from the HID git, with
the same results.

Thanks in advance,
