- 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.
