0006 USB Role Switch is a device that can select the USB role - host or
0007 device - for a USB port (connector). In most cases dual-role capable
0008 USB controller will also represent the switch, but on some platforms
0009 multiplexer/demultiplexer switch is used to route the data lines on
0010 the USB connector between separate USB host and device controllers.

0012 Say Y here if your USB connectors support both device and host roles.
0013 To compile the driver as module, choose M here: the module will be
