If the USB port on your Microsoft Surface is not working, there are a few steps you can take to troubleshoot the issue:
Restart your Surface: Sometimes, simply restarting your Surface can resolve the issue. This can reset any software or settings that may be causing the USB port to malfunction.
Check device manager: Open the Device Manager on your Surface and check for any yellow exclamation marks next to the USB controllers. If there are any, it means there is an issue with the driver or the USB port itself.
Update USB drivers: If there is an issue with the USB driver, try updating it. You can do this by going to the Microsoft website and downloading the latest driver for your Surface model.
Try a different USB device: If only one USB device is not working, try plugging in another USB device to see if it is recognized. If other devices work, the issue may be with the original USB device.
Check USB port for physical damage: Check the USB port for any physical damage, such as bent pins or debris inside the port. If there is any damage, it may need to be repaired or replaced.
Disable and re-enable USB port: In the Device Manager, you can try disabling the USB port and then re-enabling it to see if that resolves the issue.
Reset Surface to factory settings: If all else fails, you can try resetting your Surface to its factory settings. This will erase all data on the device, so be sure to back up any important files before doing so.
If none of these steps resolve the issue, it may be necessary to seek Esmond Service Centre for help to repair or replace the USB port.
