USB Port tester

[contink]

I've been finding a few problems with some USB ports that have been improperly wired up or just with some form of problem that results in USB memory pens getting fried/killed. So I've realised it would help enormously to get a bit of kit to test the USB ports to ensure they're working and wired properly.

 

Anyone found anything like this that would do the job and not instantly get fried itself?
