I have an Acer Aspire 7551
It has three built in USB ports - one on the left, and two on the right. I have my laptop on a fan, which is attached the to the left USB port, and it has two USB ports of its own (one occupied by the cord attaching to the laptop's left USB). The closest USB on the right has my mouse, and the other port on the cooling pad has a dongle that I use for my phone, video game controllers, etc). The rear USB on the right is what gives me problems. When I connect most devices to it, nothing happens. It doesn't read USB drives, it doesn't power my mouse (no light comes on) or even notice it as new a new device being plugged in, it doesn't read any devices that I plug into it. When I plug the dongle into it, the detection light blinks, but it won't detect any of the devices that it typically works with (Xbox controller and dongle won't detect each other, for example). When I plug the fan into it, the fan does receive power. The power light turns on, and the fan starts blowing. Which would be great, except that when in this port, nothing else that I plug into the fan, be it the dongle or my mouse, works at all.
What's the deal with this port? Is there any way that I can get it to actually work that doesn't involve opening the computer, or is it just broke?
