What should be done if the USB connection to a computer is not working?
To transfer data via USB cable, connect the device to the computer using the device's USB cable and select Smart Switch when the application selection pop-up appears. If the problem persists, ensure the USB cable is properly connected to both the device and computer, try a different USB cable, restart both devices, verify that the USB drivers for the device are correctly installed on the computer (download the latest drivers if needed), and ensure USB debugging is enabled in the developer options settings. If none of these solutions work, try a different port.
