Hi,
I got a eGalax TouchScreen that claim to be hid but the protocol is set
to 'none' [1].
According to 139ebe8dc80dd74cb2ac9f5603d18fbf5cff049f [2], it should be
handled by usbtouchscreen and not usbhid.
But in my case usbtouchscreen doesn't work, while usbhid work.

commit 139ebe8dc80dd74cb2ac9f5603d18fbf5cff049f

Input: usbtouchscreen - fix eGalax HID ignoring
Commit ec42d4481e36cbdb5b2801f957e678211a9e5ae2 broke
usbtouchscreen for
some eGalax/EETI devices that claim to be HID, but are not.
Devices confirmed to be real HID have the class set to HID and the
protocol
set to 'mouse'. Some have HID class but protocol set to 'none'.
Those are
not HID and should be driven by usbtouchscreen.
Fix the device ignoring macro by adding match for the protocol too.
