"Manufacturing Test Mode" After 2.5 driver update

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:

  Product ID:	0xc300
  Vendor ID:	0x17e9  (DisplayLink (UK) Ltd.)
  Version:	0.01
  Serial Number:	00000000-000000
  Speed:	Up to 480 Mb/sec
  Manufacturer:	DisplayLink
  Location ID:	0x14100000 / 9
  Current Available (mA):	1000
  Current Required (mA):	2
  Extra Operating Current (mA):	0

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

Any suggestions?
