Bug Description
In the last few days I upgraded from 8.04 to 8.10 to 9.04. This bug definitely did not occur under 8.04.
During startup, when all the normal [ Starting GNOME Display Manager ] type messages appear, they are interspersed with the repeated complaint:
[ <number>] hub 1-0:1.0: unable to enumerate USB device on port 8
where <number> is of the form ##.###### e.g. 85.013541 and increases by approximately 01.000000 every 4 messages.
I am able to log into Ubuntu normally, and my system is essentially functional - in particular, my USB devices function normally.
HOWEVER, when I press 'Ctrl+Alt+F1' to go to the command prompt the messages continue making this form of accessing a command prompt near-unusable.
I am reasonably certain this message is the result of a hardware failure somewhere along the line. The bug I am reporting is the software's inability to recover gracefully from the hardware error.

I'm having the same problem after updating to kubuntu karmic koala 9.10. When I press 'Ctrl+Alt+F1' i can always see this message:
"Unable to enumerate USB device on port 2".
