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.
