The OS, such as ChromeOS, uses Android Runtime to run Android applications. This necessitates supporting tools, for example, Android Debugger (ADB). On host to host setup xHC.DbC shall support ADB with USB. This requires user space to control USB roles. Enable user space control to modify the USB Type-C role. At run time it will create a role attribute in /sys/class/usb_role/<switch>/. Attribute can be modified based on the values suggested in the Documentation/ABI/testing/sysfs-class-usb_role.
