Aiptek T-6000U staying in relative mode.

Aiptek T-6000U staying in relative mode.

[Jan Kandziora]

Hi all,

recently I tried wanted to use my tablet again with linux-3.11.6. After
a while I found out the kernel driver doesn't succeed to bring the
tablet to absolute mode. After fiddling around with the kernel driver,
I found it is related to the order of commands sent to the tablet while
initialization. My tablet insists the absolute mode command the last
one sent. So I patched my aiptek.c as follows:

That way it works in both relative and absolute mode and the macro keys are enabled, too.

There are some problems remaining with aiptek.c and my tablet. Anyone else here who has
aiptek hardware to test if my patches break anything with their tablets?

Kind regards
