The pvrusb2 driver has a concept of "routing scheme" which defines which physical inputs should be connected based on application's choice of logical input. The correct "routing scheme" depends on the specific device since different devices might wire up their muxes Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
