No video or network with UD-3900

Hi there, currently using a UD-3900, the usb passthrough works fine but I can’t get video or network to pass through the dock.

I’ve tried a reinstall of the drivers as mentioned in other threads on this forum but I’m in the same situation.

Any ideas?

On running the plugdebug software and rebooting the dock the monitor and network have started working.



Thank you for posting, and for the quick follow-up letting us know everything is now working as expected.

Should things change in the future, please keep everything connected (even though not working) and send the output of our PlugDebug utility ( to us directly via email at and we will be happy to help.

Thank you,
