USB-C cable to connect laptop to UD-3900 dock?

I have UD-3900 docks at home and work and carry my laptop back and forth (or used to when we didn’t live and work at home 24x7). I just upgraded laptops. New one only has the smaller USB-C female plugs. My UD’3900 USB cable seems to be working with the USB-A to USB-C adapter but I’m getting some freezing/not recognizing my Logitech wireless mouse when it’s all first connected. After about 30 seconds the mouse functionality comes back. All drivers on laptop + Logitech + Plugable refreshed yesterday. Is there a cable available that can do this without the useless adapter?

Hi Bob,

Thanks for posting!

We’ve been in contact over email, but I just want update this topic with the latest details. Since we were dealing with a wireless mouse and keyboard, we suspected there could be an RF interference issue occurring as the receiver for the peripherals most likely operate on the 2.4GHz frequency band. We have a blog post that speaks to this in more detail (

This can often be remedied by removing the Logitech USB wireless receiver from the front USB 3.0 port and placing the receiver in one of the top-most USB 2.0 ports on the back of the dock.

This appears to have helped, but we’re still seeing if we can do better.

Thank you!
