I've been using a Sabrent USB-3DV since June 2014 with my macbook pro and recently upgraded the OS from 10.9 to 10.11. After upgrading the OS, I downloaded and installed the 2.5 Driver from displaylink to get 10.11 support. After rebooting the mac failed to recognize the USB display.
Digging into System Information, the adapter now shows as
Code:
Manufacturing Test Mode:

I'm not sure how to recover the device. Looks like the firmware update bricked it...
Any suggestions?
