Why is my laptop not recognizing my external keyboard or mouse through the USB-C port?

1. Check the USB-C port for any damage
2. Verify that the external devices are working properly- test on another computer or device to rule out device fault
3. Check that the correct USB-C drivers are installed or uninstall and then reinstall drivers
4. Upgrade to the latest version of your laptop’s firmware
5. Disconnect other USB-C devices that may conflict with the external keyboard or mouse
