Manufacturing Test Mode
 

Hi Everyone,

Everything was working fine until I decided to install the drivers in my boot camp partition, during the install it blue-screened. After that, the adapter seems to be permanently in "Manufacturing Test Mode". This happens both in Windows and OSX.

This is what's under the USB section in the system profile:

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: 0x1d110000 / 8
Current Available (mA): 500
Current Required (mA): 2

Connecting it to my linux VM seemed to give a little more info, something about a firmware update interface, so I am assuming maybe the firmware was being updated when the machine bluescreened or something and now it's cranky.

Hi,

Can you please let us know who is the manufacturer and when did you buy this device?

It's a Winstar WS-UG35D6 (hopefully actually a legit product).

Bought it on the 7th of Feb 2013

The chip is a DL-3500-N if that helps, here is a picture of the board: http://i.imgur.com/a9ILd4a.jpg

We have followed up with the manufacturer on this issue. Unfortunately there is no way this device can be recovered and will need to be returned to the manufacturer for a replacement.
