I'm having a problem with my USB keyboard on my new 12" PowerBook. I'm switching it back and forth between my Linux desktop and my PowerBook. Most times when I connect it to the PowerBook, it isn't detected. Disconnecting and reconnecting it a few times makes it work, eventually. The Linux machine doesn't have any problems with it-- works every time. It's a pretty generic Adesso USB keyboard and I didn't pay much for it, but I'd still like it to work Any ideas would be appreciated!
