USB device "enabled" but not working

[anna]

Since I've upgraded to XP, nothing I plug into my USB
device works, including the portable USB drive, my hp
printer, or my palm pilot (hot sync not working).

I checked device manager and went through
troubleshooting: all USB ports state they are "enabled"
and "working properly". I tried disenabling and
reenabeling. No Windows Updates are available for USB
drivers for my computer.

The USB device I am using is Intel 82801BA/BAM USB
universal host controller-2442. A colleague has a
different USB device on her XP machine (Intel 24D2).

Do I have to update my USB device or is there another
fix? Can I download it for free? If not, where do I
purchase it? Many thanks....

You could go to control panel - add/remove programs - add/remove windows components - networking service - details - Universal Plug N Play and see if it's installed!

I have a USB hub, and it isn't seen unless the above is installed!
