I’m using a UD-3900H, connected to a Sabrent USB 3.0 switch. Keyboard/headset/mouse/mic, an HDMI and DVI monitor all plugged into the dock. Dock connected to the usb switch, switch running to desktop and laptop. Everything works fine when switched to desktop, but the laptop only receives the usb devices. Display link software on the laptop shows no display devices when I swap it over. Everything transfers over to the laptop if I connect it directly into the dock, and not through the usb switch.
Is there any compatibility issue I’m missing when going through the switch to the laptop?
Thank you for contacting Plugable! I am sorry to hear that your UD-3900H docking station is not functioning as expected with your switch, and would be happy to provide additional support.
For my reference, does the problem still occur if a basic USB device like a USB wired mouse or keyboard is connected directly to the USB switch?
Next, does this issue still occur on the same port if you 1) swap the USB cables, or 2) swap computers from one Type-B port on the switch to another ? This will help isolate the cause to the USB switch, a USB cable, or a certain computer.
If the issue seems to be a certain computer, try different USB ports on that computer (USB 2.0, USB 3.0) to determine if it affects all USB ports or only certain ones.
Once I have a bit more information about the nature of the behavior, I can provide next steps.
