0008 Say Y here if you intend to attach a USB2VGA dongle based on a
0009 Net2280 and a SiS315 chip.
0010
0011 Note that this device requires a USB 2.0 host controller. It will not
0012 work with USB 1.x controllers.
0013
0014 To compile this driver as a module, choose M here; the module will be
0015 called sisusbvga. If unsure, say N.

0021 help
0022 Say Y here if you want a VGA text console via the USB dongle or
0023 want to support userland applications that utilize the driver's
0024 display mode switching capabilities.
0025
0026 Note that this console supports VGA/EGA text mode only.
0027
0028 By default, the console part of the driver will not kick in when
0029 the driver is initialized. If you want the driver to take over
0030 one or more of the consoles, you need to specify the number of
0031 the first and last consoles (starting at 1) as driver parameters.
0032
0033 For example, if the driver is compiled as a module:
0034
0035 modprobe sisusbvga first=1 last=5
0036
0037 If you use hotplug, add this to your modutils config files with
0038 the "options" keyword, such as eg.
0039
0040 options sisusbvga first=1 last=5
0041
0042 If the driver is compiled into the kernel image, the parameters
0043 must be given in the kernel command like, such as
0044
0045 sisusbvga.first=1 sisusbvga.last=5
