Troubleshooting the Samsung Mobile USB Composite Device

If you’re experiencing issues with your Samsung Mobile USB Composite Device, such as a “Cannot Start” error or a driver error, there are a few troubleshooting steps you can try.

First, check your device manager by pressing Win + X and selecting “Device Manager.” Look for any yellow exclamation marks or error codes next to the USB Composite Device. If you see any, right-click on the device and select “Update driver.”

If that doesn’t work, try uninstalling the USB Composite Device driver by right-clicking on it and selecting “Uninstall device.” Then, disconnect your phone from the PC and restart your computer. Reconnect your phone using a different USB cable or port, and Windows should automatically install the appropriate drivers.

If you’re still having issues, you can try updating your PC’s USB drivers or downloading the latest USB Composite Device driver from the Samsung website. Additionally, make sure your phone is on the latest software version and that USB debugging is enabled in the developer options.
