This is an issue of device support in the kernel first, I think.

When would this be ready? I'm also waiting on this support for a project using Chromeboxes.

I assume this is for the USB 2.0 series devices that have a kernel driver already. The newer chips for USB 3.0 don't seem to have any open source support at all.

This one should be marked done now. Pretty much all the boards are freonized now and support UDL. The only exception is nyan.

re:#7,#10 correct. Please follow bug 572763 for Display Link USB 3.0 support. (Unfortunately the underlying protocol is different and the work is not trivial)
