That 0x0400 is wierd, though ... Given that the UHCI LEGSUP register changed (a BIOS thing), I think the first thing to try is making the UHCI driver get the port back from the BIOS. It's very possible that changing that UHCI register will automatically restore the correct PORT_OWNER setting. - Dave ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
