Problem identified with my motherrboard. For some time my USB hardware
has been seemingly failing on my motherboard. This is a power related
issue. I have my MS keyboard and mouse intellipoint plugged into a Hub
with would normally not overload the 500ma limit.

The problem is the reliability of the USB ports and the amount of power
that each port can provide to the devices connected on my semmingly
faulty hardware. This is why the problem occurs now on both 8.04 and
8.10. This was solved by a PCI USB extention card and I no longer get
any errors from my USB keyboard.

Anyone else getting this error then watch the load you applying across
the USB ports and be aware that they do not always provide the full
500ma, especially when you have a cheap AMD x2 motherboard fron Nvidia.
