I am going to guess that the usb bus in question does not have enough allocated bandwidth. On usb2 that was a big problem that limited the number of web-cams usually to 1 per actual usb bus. I would suspect that removing the SSD may let the video device work. use the gui tool usbview and it should let you drill down and will tell you what other devices on the bus have allocated (assuming usb3/usb-c acts like usb2 for bandwidth), and make sure the SSD is not allocating the BW.

I'm a little fuzzy on how these things work, but I believe that there has to be support by the graphics card and driver to route the video output through the port. > > > I do not, see my journalctl output below > > > > > > [100335.446405] usb 1-3: new high-speed USB device number 11 using xhci_hcd > [100335.919043] usb 1-3: New USB device found, idVendor=2109, idProduct=0100, bcdDevice= 6.03 > [100335.919046] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 > [100335.919048] usb 1-3: Product: USB-C dongle > [100335.919050] usb 1-3: Manufacturer: VIA Technologies Inc. > [100335.919051] usb 1-3: SerialNumber: 0000000000000001 > [100340.101375] usb usb2-port3: Cannot enable.
