Question ASRock B450m Pro4 won't work with USB Docking Stations

Jan 12, 2023
Hello all,

I have been trying to fix this issues for weeks now and I have no clue how to continue. I am trying to get several different USB Docking Stations over USB3 to work in my computer with no luck. The exact error description is as follows:

USB Docking Station incl. Ethernet, HDMI Displays and several other ports works fine over Legacy USB Ports. The speed is very limited due to the limits of USB itself. As soon as I connect the dock to any USB 3+ (also the USB Type-C) connecter, the displays wont work at all. Everything else on the dock works fine just the displays dont work.

The strange thing is that it used to work a couple month ago. All of a sudden, the dock stopped working on USB 3 connects (the blue ones). But to me it looks like the ports have not issue. USB Sticks etc. still work fine. Another USB Dock shows the same behavior so the dock seems to be okay.

What I've done so far:
  • Upgrade literally all drivers to the latest version (incl. chipset drivers)
  • Upgrade Bios to the latest version
  • Tested several docks (they work as expected on my second laptop)
  • Tried all USB ports incl. USB Type-C and front panel USB's
  • Checked UsbTreeView to see whats happening. The screens are simply not there. My dock uses DisplayLink technology
Here are my specs:
  • ASRock B450m Pro4 Mainboard
  • AMD Ryzen 3 2200G CPU (Raven Ridge)
  • 16GB DDR4 Memory, running at 3000MHz
  • NVidia GeForce GTX 1050 Ti
  • Running Windows 10 64bit
I am happy for all ideas and suggestions on that issue. Thanks in advance,
