DESCRIPTION
       sisusb is an Xorg driver for SiS (Silicon Integrated Systems) video chips that are connected via a Net2280-based USB don-
       gle. The driver is not accelerated, but provides support for colordepths of 8, 16 and 24 bpp as well as Render and  other
       extensions.

SUPPORTED HARDWARE
       The sisusb driver supports USB video cards based on the following chipsets:

       SiS315E/PRO

       The  SiS315E/PRO features two CRT controllers. However, in its USB version, only the first output, referred to as "CRT1",
       is being used.

CONFIGURATION DETAILS
       Please refer to xorg.conf(5) for general configuration details and to sis(4) for more information. This manpage only cov-
       ers a subset of the supported options.

       Detailed information on all supported options can be obtained at http://www.winischhofer.at/linuxsisusbvga.shtml

       Please  note that this driver requires a Linux kernel driver as well which is included in Linux 2.6.12 and later, as well
       as available at the aforementioned website.

       The following driver Options are supported:

       Option "HWCursor" "boolean"
              Enable or disable the hardware cursor. It is not recommended to disable the hardware cursor as this will  increase
              the amount of data transferred over the USB. Default: HWCursor is on.

       Option "SWCursor" "boolean"
              The  opposite of HWCursor. This enables or disables the software cursor. This sort of cursor is slower because the
              pointer must be painted into the graphics display. This increases the amount of data transferred over the USB sig-
              nificantly. Default: SWCursor is off.

       Option "CRT1Gamma" "boolean"
              Enable or disable gamma correction.  Default: Gamma correction is on.

       Option "DisconnectTimeout" "integer"
              This  option determines how the driver will react to a disconnection of the USB device. If the integer supplied is
              -1, the driver will abort the X server immediately upon disconnection. If the value given is 0,  the  driver  will
              probe  for  a  re-connection  every 2 seconds and in case the device is detected, re-establish the display. If the
              value is greater than 0, the driver will do this re-probing within the given  number  of  seconds  and  abort  the
              server if it does not detect the device within this time-out. Default: 0 (probe forever for device reconnection).

KNOWN BUGS
       none.
