Thanks Laurie, the USB controllers are on the motherboard and I haven't upgrade the BIOS. I am not using an external hub. One of the devices, however, is a 6-in-1 card reader that connects to on of the internal USB connectors. Currently, USB devices total 4 - Epson 1640 Scanner, Epson 1200 printer, the 6-in-1 card reader, and a pointing device (trackball). I was advised by manufacturers of trackballs that I have to use the USB port rather than the PS-2 port. The trackballs did not perform well when I used the PS-2 port.
I am using the latest device drivers that are available and I will upgrade the BIOS for my motherboard.
