I did install the Epson software that came with the all-in-one. I uninstalled it and then reinstalled same wondering if a file was corrupted during the original install. It appears that either win xp or the dell tower is incapable of handling more than two items in the six port rear usb bay. If I have to live with this, then so be it. But my thinking as a consumer is, why did dell give us the six ports if they cannot support the anticipated loads? Maybe the answer is beyond we mere mortals.
Thanks everybody for your comments,
