Originally this thread was in the mobile computing section but I'm starting to think this could be a mobo issue. My USB ports decided to stop working. I'm using Windows 7 and they were working fine this morning until I unplugged my USB devices and packed my computer, then when I came home, the ports stopped working. I have two ports and I've tried placing three different items (two mice and 1 webcam) in all the ports, no avail. Even the light under my mouse isn't lighting up. I restarted twice and when I go to device manager there are no exclamation marks or anything wrong under USB tab. I even uninstalled all my USb serial controllers and restarted and they got installed back but still nothing. Then I disabled selective suspend and nothing too. I also tried going to each USB Root Hub and right click on it, left click properties, left click power management. Uncheck the box, allow computer to turn off this device to save power. This didn't work as after I restarted it became checked again. I also upgraded to the newest BIOs but still nothing. Any ideas? is this a mobo issue ?
