Product: Base System

usbdump output when the problem is seen.
When typing quickly on a USB keyboard, some characters are repeated and some
appear out of order.
Attached is the output of usbdump and the console messages with
hw.usb.ukbd.debug=2 when typing "m_count" quickly. The characters presented are
"m_counntu".
Three different keyboards tested: Two from Unicomp and a Dell keyboard. The
Dell keyboard does slightly better but the problem still exists. I do not see
the problem when using the same keyboards on a Macintosh.
This appears to be similar to the problem here:
