for the most parts, I've got an friend's XT working.
the biggest pbl. at the moment is, that with the pen, one cannot reach the border of screen on the left, right and bottom. there is a 1,5 cm "deadzone", which cannot be reached with the pen. the curser jumpes back towards the middle, if you try to move it i.e. to the corner.
I tried to read the firmware-ver. with no success. the calib.sh/frimware runs, but returns only zeros for firmware.
BIOS is A09.
it did work under windows.
does anybody has a clue, where to start?.
any help appreciated,
