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?

Take a flashlight an shine it into the problematic USB port: Notice anything untoward? And bent/broken/missing pins noticeable?

Has it ever worked properly?

Thanks

On the inside it looks exactly the same as the functional USB port next to it.

 

I don't remember if it's ever worked. It used to be the port that I plugged the fan into. As said, the fan always, and still does, turn on when plugged into it. But it was when trying to plug things into the fan while the fan was in that port that I noticed it didn't work right.

Maybe uninstalling the USB controllers via device manager and rebooting will help. (?)

If not maybe updating the drivers?

Sorry about the belated reply as we have been busy of late.
