Powermate is the one with big aluminum knob, isn't it? I have it.
I'll look at this, although not sure when.

Comment 4 Juha Tuomala 2007-11-12 19:17:25 UTC

yep, that's it.

I was writing a python script for kmix using kde dcop to alter my background 
noice level and now with f8 can't read it. 

I'm not sure is that important, but noticed that with fc6 that you can 
different bytes out of it depending do you rotate it (two directions), press 
it, or press+rotate it. Don't remember did it have 'double-click' separately.

Comment 5 Juha Tuomala 2007-11-12 19:18:58 UTC

And a site note, should there be some udev rules for getting rights for it for 
console user?

Comment 6 Harald Hoyer 2007-11-13 08:09:59 UTC

use hal and ACL for console user rights

Looks like the gizmod would be the modern way to hook powermate to desktop.
