If you use the AirDroid Personal Desktop Client to run a Non-Root setup for an Android device, you need to connect the Android device to a computer via a USB cable. But sometimes, the computer may not recognize the Android device or failed to connect to the Android device via USB cable. Here is the troubleshooting guide:
1. Go Developer options and re-enable "USB debugging"
2. Go Developer options, tap “Revoke USB debugging authorizations" - "OK", then re-connect the USB cable, and a pop-up window "Allow USB debugging" will appear, please select "Always allow from this computer" and tap "OK"
3. Change the USB mode
- For Android 8.0 and above: please set the USB mode to Charge Only (otherwise, the non-root will get failure after disconnect the USB cable)
- For Android 8.0 below: please set the USB mode to MTP
4. Use another USB Port of the computer and use another USB cable.
5. Restart your Android device and restart your computer
