Thanks for reaching out to us for assistance! I’m sorry to hear that your Plugable product is no longer working as expected, and I will be happy to assist you with this.
Our first troubleshooting step would be to run through the DisplayLink Driver Cleaner Steps → https://kb.plugable.com/docking-stations-and-video/373346-my-displaylink-based-dock-or-adapter-is-not-working
If this does not resolve the problem, I would then ask for you to run our PlugDebug diagnostic tool. If you do run the PlugDebug diagnostic tool please send the generated ZIP file to our support email → email@example.com reference ticket #381617.
If you do so please keep all devices connected to the Plugable product that you normally would (even if they are not working!). Once PlugDebug has finished there will be a newly exported file located on your desktop, please attach that file in your next reply to this ticket. In order to run PlugDebug please follow our step by step instructions located here → https://plugable.com/pages/plugdebug
Once more we apologize for the trouble.
