A customer of mine had a computer that died, with a touch screen on it (IIyama ProLite T2252MSC). I had the customer put the touch screen on a Raspberry Pi running Raspbian, and customer now complains the touch screen barely reacts to touch, you need to press very hard to get a reaction.

I don't know if that screen conforms to Windows Touchscreen Collection, nor do I know much about USB HID touchscreens in general, but from the link before, it seems that a touch screen may report presure.

Is there way to adjust how much presure would be needed to trigger a "click"?

Looking for things about Weida Hi-Tech which seems to be the touch panel manufacturer, I came across this forum thread.

Somebody there suggests adding "usbhid.mousepoll=0" to /boot/cmdline.txt, tried it, it fixed the reported issue.
