External camera does not work in Ubuntu 22.04.3 LTS

[jbygden]

Hello!

I installed displaylink-driver (5.8.0) and evdi (1.14.1-7) and tried this with one of our Logitech Rally Bar (https://www.logitech.com/en-us/products/video-conferencing/room-solutions/rallybar.960-001308.html) installations. Physical connection is via a Logitech Swytch (https://www.logitech.com/en-us/products/video-conferencing/room-solutions/swytch.952-000009.html) It's connected to a 65" Samsung TV.
I get sound from the Rally Bar, picture on the TV and the microphone belonging to the Rally Bar is used.
But - I the camera in the Rally Bar is not working, it show's up in both Zoom and the built in Cheese app (https://help.gnome.org/users/cheese/stable/), but it's not selectable.

Anyone else got this to work? How did you do it?

USB ports use standard USB drivers - DisplayLink does not affect them in any way.

You should rather contact Logitech and ask them. But usually, it is strongly recommended to connect any cameras directly to the computer and not use any HUBs or docks as cameras may not work correctly in such cases.
