Unresponsive USB devices can be a common challenge. Ensure the USB device is properly connected and recognized by the Switch. If not, try using a different USB port or cable. Restarting the Switch can also resolve connection issues.

For unsupported USB devices, consider using an adapter or hub that is compatible with the Switch. Check online resources for recommended adapters. If the USB device requires specific drivers, explore using a computer to install and configure them before connecting to the Switch.
