usb ports
I have a Dell dimension 8100 with Windows 2000. It has 4 USB
connections built in in the back. I presume that is what is called "a hub". I have had recent trouble installing a 3200 Epson scanner. Epson tells me that the scanner has to be installed in a "self powered first tier configuration". I presume that plugging the scanner directly into the computer back is first tier, but how do I know if it self powered?. I realize I may have other problems, but first I have to be sure that the computer meets the requirements. Thanks.

Self powered and externally powered. Self powered draw their power through the usb cable itself, externally powered plug into the mains. Since your ports are on the back of your machine they must be self powered. Just whack it into the back of your machine and it'll most likely auto-detect for you. Hope this helps

In general, plugging it directly into the back of the PC will provide
sufficient power, and would be first-tier. "Magdalena Reissig" wrote in message om... I have a Dell dimension 8100 with Windows 2000. It has 4 USB connections built in in the back.
