DisplayLink on Fedora

Here's a surprising story of a piece of unusual hardware working with less effort on Linux, than on Windows.

I bought one of these of ebay -

DELTACO USB 2.0 till DVI/HDMI/VGA-adapter

Planning to use it on a custom x86 board I have, that doesn't have a graphics adapter. First trying it on Windows 7 - where it worked fine, after downloading and installing the drivers.

I then booted Linux, expecting to again download drivers, and likely need to compile them, with the usual dependency nightmares...

However, on boot, the display came up by itself :)
