Comment (by X512):
Finally I got touchscreen working on Haiku! It is working, but with report
id 4 hack and multitouch isn't handled correctly.
As I read from Microsoft documentation HID device can had many reports.
Haiku HID driver create device for every report id. Is this correct? Also
tablet input_server device can't handle more than 1 device correctly.
I changed mouse generation logic in tablet add on: now B_MOUSE_MOVED
message generated before B_MOUSE_DOWN / B_MOUSE_UP. Without it most
applications didn't handle mouse messages correctly. Some issues with
event handling still exists in menus.
I don't think that patch is useful because it is hardcoded to Acer W500.
HID report handling should be changed to remove hack.
