So many instabilities with Dell USB 3.0 Dock
 

I bought 18 of the Dell SuperSpeed USB 3.0 docks. With over half of them, they randomly refuse to output video. Sometimes we can reset the docks and it works, or I can remove and reload the software. The laptops these connect to are Dell Latitude E6430U systems. All were created from the same image.

Dell has been less-than-helpful with troubleshooting, so I wanted to see if anyone here has had the same issues with these docks.

I have replaced a few that we simply could not get working, and have noticed they are stamped A02. The ones I originally ordered are either listed without a revision, or A01. I have my fingers crossed that this is a resolution.
