I am running Windoze 98SE and (so far) have had no problems.

I don't know what kind of computer you have but some motherboards have kind of a "built-in" hub, and a main USB port. I would suggest that you unplug all your USB stuff, and try all the ports one by one with PENG.

Then if that does not work, UNINSTALL ALL the USB stuff (scanners, printers, etc.) and then try PENG.
