Did Norton 2010 corrupt my USB ports

[BrianG]

Well, the USB ports themselves are ok since other devices work. So, to me, that would mean the USB driver for those devices somehow got corruputed.

Are any of the other devices "high speed"? Have you tried transferring a file to make sure it fully works, or did you just see if the PC would recognize them? I'm thinking that maybe the USB2 driver maybe got hosed, not the specific device driver. Go into device manager and try updating the driver of the devices under "Universal Serial Bus controllers".

Or, maybe try to rollback using a previous system checkpoint.
