Hi Sandy,

Thanks for getting in contact with us. I’d be more than happy to help you with your Plugable UD-3900. In order to better assist you, I’ll need a bit of additional information.

Could you please provide the logs produced by our tool Plugdebug, you can find it here and then send them to me at

Once we have those logs, we’ll start trying to figure out what exactly is going on with your setup.
