+config USB_SISUSBVGA
+ tristate "USB 2.0 SVGA dongle support (Net2280/SiS315)"
+ depends on (USB_MUSB_HDRC || USB_EHCI_HCD)
+ help
+ Say Y here if you intend to attach a USB2VGA dongle based on a
+ Net2280 and a SiS315 chip.
+
+ Note that this device requires a USB 2.0 host controller. It will not
+ work with USB 1.x controllers.
+
+ To compile this driver as a module, choose M here; the module will be
+ called sisusbvga. If unsure, say N.
