I own a SONY Via computer.  IT had been working perfectily -- until now.  The USB drives are not being recognized at all (even an old jump drive) is not being read.  The problem or error states that the USB hub in not being recognized or is having a problem.

Sounds like the power side might have gotten fried.. Do you have a powered USB hub you can try?  Most likely the only fix is a MB replacement.  

You can also try reinstalling the chipset drivers.. download them from Sony for your model.

misterd--This reference has lots of ideas
http://ntcompatible.com/Desperately_need_help_---_USB_Devices_Not_Recognized_t32356.htmlThe one that helped most posters was
"unplugging the power and letting it sit for 30 min."
Perhaps more ideas

open device manager - any errors there?   report back
you can also install or update your chipset drivers, it can help
you can also delete all the usb entries from device manager, REBOOT and test
