Thanks for posting, and I would be happy to help!
Can you let me know exactly which Plugable product you are using? I’m guessing one of our USB video adapters or docking stations but I’d like to make sure which specific device is being used.
Pending that information, I’m not quite sure I understand the sequence of events based on your description. Can you provide some additional detail about what actions you are taking and the resulting symptoms?
Let us know the additional information when you have a moment and we’ll go from there.
