Help text

USB Role Switch is a device that can select the USB role - host or device - for a USB port (connector). In most cases dual-role capable USB controller will also represent the switch, but on some platforms multiplexer/demultiplexer switch is used to route the data lines on the USB connector between separate USB host and device controllers.

Say Y here if your USB connectors support both device and host roles. To compile the driver as module, choose M here: the module will be called roles.ko.
