USB Ports

I have a Dell 4500 desk top, running XP Home, and a Compaq 2500 laptop, XP Professional.
My question is this, are all USB ports functional or do they need to be activated in some fashion.
On both computers some ports seem to work while others act as if they are not functioning.
Thanks for any help provided.

Should all be active always

If this isn't the case, it's probably a hardware issue. Either a damaged port or damaged controller. Neither of which is good.

Have you looked in the BIOS to see

if any need to be enabled. Some have a mix of USB1 and USB 2, and the 2 has to be enabled in some.

Any chance that is the front vs the rear???

USB Ports

The desk top has two ports in front and 2 in back of the tower. I usually go into the back as the fronts give me a problem.
The laptop has one on the right side, and two stacked on the back right corner. The side port seems to be working ok.
