Re: pbbuttonsd beta on new Powerbook5,8
Hi all,
On 22 Jan, this message from Michael Schmitz echoed through cyberspace:

Doesn't seem to be the case...

Correction: it does seem that running mouseemu blocks the special keys,
as well as blocking pbbuttonsd's keyboard activity detection.

Obvious. However pbbuttonsd does rescan devices, so after the rescan
interval it will catch changes in event devices.

All 32 event devices are there (udev disabled). mouseemu does create
it's event device corresponding to /dev/input/uinput. If mouseemu
wouldn't relay keyboard events, the keyboard wouldn't work at all.
It seems to be more a problem of mouseemu filtering out _some_ events?

As it clearly is mouseemu related, I'll check that path.

But it seems the earlier patch simply didn't work. Anyway, that part is
working now.
Thanks, and cheers
