Say Y here if you want to use an ATI or Philips USB RF remote control.
|
||||
These are RF remotes with USB receivers.
|
||||
ATI Remote Wonder II comes with some ATI's All-In-Wonder video cards
|
||||
and is also available as a separate product.
|
||||
This driver provides mouse pointer, left and right mouse buttons,
|
||||
and maps all the other remote buttons to keypress events.
