I have a HP Compaq L2206tm USB touch screen here. It works right out of the box in windows XP SP3, no 3rd party drivers needed.
However, it doesn't in Fedora 17 and Mint 13. In fedora I get some output in dmesg stating it's a TPV OpticalTouchScreen whereas Mint doesn't say anything about it. I've also checked /dev/input and /dev/usbmonX and nothing there relates to the screen in both distros.
xinput doesn't list the screen either.
I went in XP and although the screen is brand new, I THINK XP uses some kind of generic driver made in 2001 so my guess is that it should also work in Linux in some way.
Anyone has some clue on what I could do to get it to work under Linux?
