Targus USB3 docks video stopped working almost right out of box

[mattgores]

I was setting up a Dell XPS14 laptop, plugged in a previously used dock and no monitors were detected. All other devices looked normal in device manager.

I tried another dock, plugged it in, updated firmware - great! Rebooted the PC and the monitors were no longer detected. They appeared to be getting a signal since the screens were black, but they were not detected in the OS.

I tried a 3rd dock, plugged it in, updated firmware and it finally persisted post reboot!

I've tried the 2 bad docks on other PC's and can't get them working. Are they dead and do I need to RMA?

Attached is the log from one system w/ the problematic dock and one DVI monitor attached.

Thanks.
