I use a USB keyboard (Macally iKey) and mouse (Logitech iFeel) without
problems. I also get these messages, but I dont see any performance problem.
It may help you to enable an option like "Legacy USB keyboard support" in
your BIOS. This will emulate a PS/2 keyboard until USB is initialized.

This was discussed in the USB mailing list a few weeks ago. Several people
experienced this problem, including me. As a workaround, use the alternate
UHCI (JE) driver.
