I was going to charge a remote control helicopter from my laptop USB port and accidently plugged the end going in to the helicopter in the wrong way
. The helicopter went on even though the switch was in the off position and I unplugged it right away. When I tried again after correcting the mistake the USB port wouldn't work. The other USB ports on my laptop stopped working too. They all use to work. I have a wireless mouse that I use and it's not working. I tried uninstalling all the USB drivers
and restarting, but that didn't work. I also tried turning off the laptop, unplugging the ac wire, and removing the battery for a minute. I tested the ports out with the mouse and it still doesn't work.
