My UD-3900 intermittently freezes and need to be power cycled

My Plugable UD-3900 seems to freeze up and stop working intermittently. I have to power cycle it to get it working again. The only thing I see in the event viewer when this happens is this error, “Plugable Ethernet : Has encountered an internal error and has failed.”

Hi Steven,

Thanks for reaching out to us. I’d be happy to help you with your UD-3900 intermittently freezing.

Since this sounds like a fairly complex problem, it would be best if you could gather some additional information for us. This is most easily achieved by running our log gathering tool Plugdebug.

If you could email those logs to us at
