hello all, i'm a newbie.

and i'm really frustrated and looking for help.

recently purchased a dell optiplex gx280 from a local retailer at the mall that was going out of business, so they formatted the hard drive.

I loaded an old copy of xp professional that i had and used the old product key and downloaded all the drivers from dell.com.

everything is fine but the usb controller has a question mark.

and when i plug in anything in to the usb it states high speed usb plugged into a non high speed usb hub.


seems the only fix i can find to this is to have service pack 1 or greater.

however when i attempt to download service pack 2, it has a problem with the product key.

so i formatted again and tried a fresh install of windows and tried to use the product key on the side of the pc, it would not install. so i had to use the old key again.

I've tried everything, i downloaded the unkown device identifier tool to attempt to resolve but no luck.

is their anyway i can get my usb 2.0 hubs to perform as they should?
it's driving me crazy!

please help

sorry for the length, just wanted to be as detailed as possible.
