| help |
| 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. |
