Can anyone give me some advise on this please!! so I was testing a clients credit card reader and as soon as I plugged it into my son's Macbook Pro it shutdown completely. No green light, no NOTHING! I found that the credit card reader that has a power supply (walwart) was delivering 10V into the USB cord!! Totally killed my boys computer. I know I should start with the one wire right? Figure out why it's not getting power. Check the battery. What about USB? Just wondering where I should start knowing that it was killed because of voltage into the USB?

Thx.
