[PATCH] Map MS Presenter 8000 bottom-side buttons

[PATCH] Map MS Presenter 8000 bottom-side buttons

[Jan Kiszka]

The MS Presenter 8000 bluetooth mouse is a "dual-use" device: If you press a button on the top, you can turn it around and find special keys on the other side, useful for presentations. This patch maps those three bottom-keys that are not already detected to the intended functions. The magic bottom on the top is mapped to F5 when we switch from mouse to presenter mode in order to activate the presentation mode in the related software (e.g. OpenOffice).

Hi Jan,

could you please take a short look at current Linus' git tree - there are 
some more devices using MSVENDOR page, and we have introduced macros to 
match them. It would be great if you could redo the patch to fit into this 
picture and send it to me again.

Thanks,

OK. Do you mean something like this? Sorry, in a hurry, not even
compile-tested...
