Sorry to hear that your "Thumb Drive" failed during a data transfer ! I would check it out on another machine and return it to the supplier if its still in warranty. Without testing the port on the machine itself, its very unlikely that the port is **miss wired or has failed. If you have a multimeter you can check the voltage on the pins. The maximum voltage you should see is +5 volts. This will only be on one of the end pins. Under No signal conditions, the other three pins should not have any voltage on them at all. Without access to a dynamic tester this is about all you can check for. I am not aware of any commercial tester for these ports, so I built my own. **For a few early mainboards, yes there are some that have the power connections the wrong way round (I am talking about Hard wired ports) Not those on pin headers, where you can make a mistake when connecting then up. These will kill a "Thumb drive/USB Key" stone dead the instant its plugged in. However some devices do have reverse voltage protection. The effect with these is that the device simply doesn't work on that machine, even though Win says its working properly !!
