Tried all the different ports I could. Seems I can't get it on the EHCI buses no matter which ports I use. Even replugged the front USB cable to the other ports but it always comes back on the two OHCI busses. Am thinking of buying a separate PCIE USB card as a temporary work around... I've had to cancel my studio sessions for the week on account of the systems being down. ARG!

URB is kind of a bulk transfer protocol. Not sure what this error
message means without digging in.

Try plugging it into different USB ports. Looks like you're sharing
it with a mouse or something (possibly internally on the MoBo).
