xp sp2 disabled all usb ports

[Craig]

After installing xp sp2 I can no longer use my wireless
keyboard and wireless mouse as well as my usb memory
device is not detected either. I have seen something
regarding security issues with usb devices after an
upgrade to sp2. Any help out there??

Try reinstalling your chipset drivers if possible. These are on the
support CD for your motherboard or you can go to your motherboard
maker's website and download the latest version. Even better if you
know what chipset it is, then go to the chipset maker's website and get
the drivers there.

To get my USB back after SP2 all I had to do was in Device Manager
select Update Driver for the first few USB entries
