Subject: Re: [PATCH] SISUSB2VGA driver add 0x0711, 0x0903

Sorry, but since it was so an "easy" patch I thought it was not needed :P
I add some more information;
This adds a new device I bought some time ago from www.compatible.eu, 
but Its produced by Startech (www.startech.com).
Looking the device VID and PID it seems the normal evolution of the 
previous products supported by the linux driver sisusb2vga.
It permits to add an external display using a normal usb2 port to your 
computer. Up to 16 displays connected to the usb (in theory) with a 
maximum resolution of 1280x1024 and 32bits. The only problem is the lack 
of acceleration and the poor refresh rate, but it works quite well for 
mostly static display (for example your mail software).
I've been using it for nearly a year without any problem using xinerama 
configuration on xorg.
I've had had also reports from some people using it without problems 
(see http://www.sidux.com/index.php?module=pnWikka&tag=usb2vga ).
For more information and pictures just have a look at;
