Less than a year old means it`s still under warranty.
Be aware of this before doing anything physical to it ;)

The standard fix for this problem is to 'uninstall' the USB ports,then re-start the computer and let Windows re-install them.You have to go into the 'Device Manager' to uninstall them.

If that doesn`t work,contact Toshiba support for their suggestions.
They may ask you to do a 'factory restore' (just resets everything to the day you bought it).
