USB Over Current Notice

Hello and help...
I've a Mac Book which I lent to a friend for the weekend and they rather stupidly tried to test an external CD player via the laptops USB ports. Apparently the laptop powered down and now everytime I power up the laptop this message appears.
"USB over current notice. A USB device is currently drawing too much power. The Hub it is attached to will be deactivated".
The laptop powers up ok and all other applications seem to be ok. There's nothing connected to the USB ports but as per the message, I can't use anything via it, like web dongle, memory stick etc.
Any idea's as to how to reactivate the USB ports safely?
