Hi Edward,

All your USB ports on your Dell PC/laptop are plug and play. If you are facing issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.

1. To Identify a Working USB Port
Check Device Manager to see if your USB ports or hubs are working properly.

1. Click the Start button.
2. Click Control Panel.
3. Click Hardware and Sound.
4. Click Device Manager.
5. Double-click Universal Serial Bus controllers and check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
6. If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.

2. To Run a Diagnostic Test on your USB Port
Dell has provided an online diagnostic tool to help identify and fix issues with your system.

1. Go to the Dell PC Diagnostic page
2. Click the Advanced tab.
3. Ckick Hardware.
4. Using the scroll bar on the right-hand side of the window below; locate the listing for USB.
5. Select USB.
6. Click Run Diagnostics.
7. Agree to Terms and Conditions in Legal Statement.
8. Follow the instructions to test each USB port.

3. See the hardware changes
Run "devmgmt.msc" to open Device Manager. Under Action tab, select Scan for hardware changes and see if it helps.
4. Update the drivers
Check if you need to update your drivers.
Open Control Panel -> Printers and devices.
Check if you can see any entry for Unidentified USB device or Unknown Device. Open its Properties and update its driver, if an update is found to be available.

Finally, you can have a restart of the Windows machine by unplugging your USB and see if it gets detected then.

I hope this helps in solving the issue with your USB port.
