The Android Composite ADB Interface driver is used to enable Android Debug Bridge (ADB) communication between your Android device and your Windows computer. ADB is a versatile command-line tool that allows you to interact with your Android device for debugging, application management, and other advanced tasks, such as copying files, installing APKs, or running shell commands.
This driver specifically allows your computer to recognize your Android device in ADB mode, which is typically used by developers or advanced users. When you connect an Android device to your computer via USB and enable Developer Options and USB Debugging on your device, the ADB interface driver enables the connection between your device and computer for debugging purposes.
