Hello!
Sending patch as told to.
Formal notes:
Patch made against 2.6.22.9 sources.
Marketing is lying, quick google for model ( TL6B17S) shows they say
it has 4096x4096 sensitivity, while device itself do not report more
than 0x0470 (i set 0x0500 as max), so with monitors greater than 1024
pixels special calibration is needed.
I wrote mail to manufacturer asking for linux drivers but got no
response, so i had no way but to sniff the usb bus and figure out how
to make the device work, and reversing is not illegal in my country.
I agree with GPL of course, the following patch can be used according to it ;-)
hope that's all
regards,
Ilya Frolov
