HELP none of my USB drives are working :(

i posted this in the sofware form also because i really am not sure where it belongs so, sorry for the double post.

well first of all merry christmas. but i do have a slight problem. none of my usb drives are working, not even the ones on the MOBO. they wont work for the mouse, a pen drive, or ipod. i dont know what to do. i have uninstalled all of them then serched for new hardware and let windows install them. i also restored a registry backup from a couple of weeks ago. i think they were working then, but im out of ideas what do i do?

 

Sounds like a USB or Motherboard problem if there not working
