When the TBT3-UDV is used with certain Windows 10 or Windows 11 systems, there is a possibility that two of the USB 3.0 ports located on the back of the dock (closest to the Ethernet port) may not be recognized properly by the operating system. This issue is not present when the TBT3-UDV if used with an Apple Mac system running macOS.

Should this occur, while the dock is connected to the host PC (this is important) please download and install an updated Asmedia USB 3.0 Host controller driver from here and reboot the system and test the behavior again. 

If that does not resolve the issue, please reach out to us directly via support@plugable.com and we will be happy to help.
