USB 3 to HDMI Adapter NOT working on MBP (10.9.5)

[tstanley1]

Hello

I have tried several different cables (latest cable was "Displayport to HDMI") with Adapter plugged into Apple display or MPB USB 3 port. Monitor works fine if I use a "Dsiaplyport to DVI" to MBP. Nothing I try with adapter brings the additional screen to "life". It is not recognized. But the adapter does show up in the system USB 3.0 SuperSpeed Bus list...so that is working.

I am using the latest Mac driver 2.4.

I have attached the appropriate logs using your tool. Please help me troubleshoot this...otherwise, I will be forced to turn in extra monitor to NASA property...and we don't want that

No we don't want that to happen!

Unfortunately the logs show that there is no monitor detected at all. We're really looking at a hardware fault here.
Being an HDMI adapter we usually think about a problem with the cable or the adapter to DVI or VGA.
From what you say it looks like the monitor is DVI and it is working OK. So one of USB to HDMI adapter or cable or HDMI to DVI adapter has a problem.
To find out I'd suggest to borrow equipment and verify the different stages of the HDMI connection.
