Hi Peter,

your device presents Contact ID, Tip Switch, In Range and Confidence.
I would say that Win 7 would treat it as a multitouch screen, so this
might work with hid-multitouch. Please note that's the first time I
see a report descriptor with only one touch reported for a multitouch
screen.

For the configuration, the device may emulate a mouse by default, and
hid-multitouch is able to switch to the multitouch mode. You will
loose the right click, but it can be enabled in gnome at least
(accessibility settings).

Can you just replace in hid-ids.h:
- #define USB_DEVICE_ID_CRYSTALTOUCH 0x0006
+ #define USB_DEVICE_ID_CRYSTALTOUCH 0x0005

and see if it's working?
If you prefer, I can make a new patch, but I'll need to know which
kernel you are running (tree and branch). A 2.6.39 and above would be
great.

Cheers,
Benjamin
