Well I know your problem has been solved but for others that this didn't work, what worked for me was going to right clicking on the windows button (usually at bottom left) and going to device manager. Then scroll down to Universal Serial Bus Controllers, click the arrow to the left of it and go to Generic USB hub. If there is a caution sign by it you we're most likely in my situation. To fix this right click the device and click Disable Device. After that re-enable it. This hopefully should fix it.
