This is very interesting, I have access to a 65" IrTouch system which
has VID 0x6615 and PID 0x0C20. I wasn't aware that there are already
kernel drivers for their systems, I had been playing around with their
awful binary driver and had done some experiments with libusb. Is there
a documentation of some kind available?

I will test this on our screen next week.
I assume that I should use the tree from:
Note: after briefly browsing through hid-multitouch.c, it seems to me
that there might be issues; the USB interface on our screen doesn't
report as HID device, but as vendor class (0xFF).
