What happens if you short the ground and VCC of a USB port?

There's just 0.5 (A)*5(V) = 2.5(W). What harm can 2.5 watts do?
I wouldn't want to try that, personally...

Your voltmeter tests show there is something wrong with the port. You need to find and fix that problem first. If you're lucky, it just a resolder of the USB jack.
