Vista; USB Mass Storage not in Explorer, Disk Management

Hey,

I recently re-installed Vista, and now, all of my Flash Drives, my iPod, etc., dont show in My Computer or Disk Management. When I plug them in, Vista DOES recognize them, dings, and puts them in the 'Safely Remove Hardware' menu like normal. My iPod doesnt show in iTunes, and my Flash Drive/iPod both show in Device Manager...

I know its not my USB ports, because my XP x64 dual-boot works fine... To add to it, my USB keyboard/mouse work fine in Vista, and my PDA is recognized, so that shows that the USB support isnt corrupt...

thx
