I have a USB hub UH700. I have noticed that if I happen to catch the metal part of the usb plug that goes from the hub to the computer I get a quick shock from it. I grabbed hold of it ready to put into computer when I got a quick zap. It's the original cable and the hub is powered with the original adapter.

Is this normal with a powered hub??

Not sure if I want to plug the usb lead into my computer if it's not supposed to.

Cheers
