Hi all,
sorry for neglecting this thread for so long. And thanks Ulrik for
pointing me to the formalities.
I was kind of surprised at first that the value was 0x33 instead of 0x3
until I read the documentation pointers Julian provided.
It seems like some kind of softswitch or masking for the individual
buttons. One of the 4-bit nibbles indicates the number of available
buttons in hardware, the other one the number of activated buttons.
I really would like this patch to become part of the linux kernel and
I hope that Julian will go through the formalities for patch submission.
I'm willing to do so, but I'm very short on time currently.
Additionally, I checked on a Thinkpad forum and was told that there are
Thinkpads from the 90s with two buttons (e.g. ThinkPad 760 and those
before ThinkPad 390/600/770). So I'm a bit afraid that simply setting
the default to three buttons may break something for these models and a
more elaborate patch may be necessary.
Kind regards,
Julian
