I have some minor non-working thing:
after rebooting mouse not works on PmacG5 Quad.
ERR: wrong port status 0103 for port 2
strange port response, power-cycling port 2

Restart of Poseidon stack not helps, unplug and plug the mice yes.

I don't know if it is connected with MOS (on G5 linux & MacOS mice works) or I have bad mouses ( my Powerbook G4 have the same error).

Do you have similar issues with Mac&Mouse ?
