Specify the plugin to use. If you have installed more than one plugin (XA1541, XU1541, XUM1541), you can specifiy which one to use for this command. This way, you can use all three variants at the same time.
This requires an argument of the form <plugin>[:<bus>], where <plugin> is the plugin's backend name (currently: xa1541, xu1541, xum1541), and <bus> is the bus identifier, if it is supported by the backend.
