Hi,

I recently had to move my Dell 4600 to another room, when it was cabled up I found that only 2 of the 8 usb ports would support devices. After a little investigation I found 2 more. I cannot get the other 4 to work with anything at all? There are no obvious clues in device manager.
Has anyone any idea what is going on.

I am currently using them for:

printer: Canon MP180
Seagate 13400 40g external drive.
iOmega 250meg zip
2g Kingston flash

OS Win XP home
