Displays and ethernet not detected, Plugable UD-3900
1 Attachment(s)
Hello
I have a Plugable UD-3900 It is connected to a System76 laptop running PopOS (an Ubuntu derivative) Code:
$ uname -a At some point I've detached one of the monitors and simplified the desk a bit, but now neither of the video ports are detected (there is an HDMI and a DVI port on this dock), I've tried a combination of cables, all tested on other devices. Neither does the ethernet connection work - getting "Cable Unplugged" error. All USB ports are still appear to be working, I have a keyboard a mouse and an external storage attached to it. I've checked all the cables by plugging them directly into the laptop. I've also tried the dock with a MacBook, the USB devices seem to work fine, but since this MacBook doesn't have USB3 port I didn't really expect it to get video. I've tried the dock with a Chromebook ASUS C101 (by using USBA-to-USBC adapter since on this chromebook USB-3 is only supported through the usb-c ports) -- same result, the USB devices such as keyboard/mouse are ok, but no video or wired network. I've downloaded and ran the DLSupportTool, and I'm attaching the output here. When I ran the tool, only the HDMI cable was plugged into the dock, hopefully that simplifies the diagnostic somewhat. I don't think I've dropped the dock at any point or done anything to damage it, but something has changed, hope someone here can help me figure out what. |
