I have a Dell Inspiron 15 laptop with Windows 8.1 installed. The laptop has two USB ports. One of them, which is the only one I use, suddenly stopped working while the devices were plugged into it.

 

I plugged the failed devices into the second port, and they worked fine. Knowing that the problem was the port and not the devices, I started troubleshooting it by restarting (several times) and looking in Device Manager.

 

In Device Manager, a USB device has a yellow warning sign and it says "Unknown USB Device (Set Address Failed)." I uninstalled this device and restarted, but it just says the same thing again. If I click properties, the device's status is "Windows has stopped this device because it has reported problems (Code 43)."

 

I should also note that when I plug a device into the bad port, it lights up, so it seems to be getting power from the port. The devices don't seem to have any corruption or data loss.

 

Thanks for any help.

Open the Device Manager and right click on the first device at the top of the tree.  Select Scan for hardware changes.  This will force the USB port to restart.

Okay, I did that and it has the same status. The port still doesn't recognize any devices plugged into it.

Is the yellow warning icon in one of the USB options outlined in red below?

Sorry about the late reply. No, the device doesn't seem to be one of those, although since its name is "Unknown USB Device", I don't know what its original name was. I attached a screenshot of my devices.

Try this.  Remove all USB devices except for you keyboard and mouse, start the computer and see if the warning icon is still being seen.

That's what I'm already doing. The only USB device plugged in is my wireless mouse, and that's how it was when I restarted.

See if disabling USB selective suspend helps. You may need to reboot.

Unfortunately I've already tried that as well on the day the problem occurred. Sorry I forgot to mention it.

Something else to try.

 

Turn off laptop, remove the power lead and take out the battery.

 

Press and hold the power button in for 20 seconds or so.

 

Have a look around the room for a minute or so (optional :))

 

Plug power lead back in and start machine.

 

When machine is fully loaded try usb port again then put battery back in.

If opera's suggestion does not work then it could be a hardware fault on that one port. Boot a live linux disk like Fatdog. Attach a flash drive. If you do not see a USB icon pop up on the lower desktop in that one port but in your known good port then you know it's hardware.
