Hi,

to answer Matthew Carpenter, I own an ASUS MB168B+ and no, it isn't
working in the latest 14.04 releases...

I'm still in the process of reading all I can find about this problem,
but so far, as everyone, I can't find any clear instructions about "how
to make it simply works"...

My notebook is an ASUS G75VW
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

I'll add an apport report from my notebook if it can help...

Title:
  17e9:0378 [Lenovo ThinkPad X1 Carbon] Regression: DisplayLink DL-195
  fails with EAGAIN after upgrade from 3.11.0-031100  to 3.11.0-11

Bug description:
  My Plugable UGA-2K-A USB 2.0 to DVI adapter (using chipset DisplayLink DL-195, USB ID 17e9:4302) works fine with 3.11.0-031100-generic. However, when upgrading to 3.11.0-11-generic, X11 fails to open the DRI device with:
  [     8.868] (EE) open /dev/dri/card1: Resource temporarily unavailable

  Reverting to  3.11.0-031100-generic fixes the problem. Upgrading to current mainline (3.12.0-999.201310030405) also fixes the problem (but causes lots of kernel BUG messages).
  In both cases, the kernel correctly creates the /dev/fb1 and /dev/dri/card1 devices. There are no error messages in the kernel log.
