I have a Thinkpad P14s Gen2. It has an integrated webcam. That webcam is not shown in the usb attachement GUI.
When I connect an external webcam it is shown in the usb gui, but when I connect it to a qube it is not being recognized there in Jitsi Meet or cheese. I already increased the maximal ram in sys-usb.
Is your webcam enabled in the laptop’s firmware? (by firmware, I mean the thing that we used to call BIOS)
Yes, it also worked before when I was using Arch Linux
Let’s try to find the integrated webcam first. Thist is lsusb in sys-usb:

``AFAIK if you see the “USB Billboard”, it means that the auto-detection and/or negotiation has failed, and the “real device”, in this case the webcam, is not available.
The USB Billboard device is like a business card handed over by the (complex) device, so that the host can load the appropriate drivers. Google knows all about it.
I only found issues online where people saw a USB billboard device when a monitor was not working properly and it seems to be related to usb C displayport alternate mode.
@besen Have you tried to downgrade the kernel of the appvm you want to attach your webcam? (in settings–> Advanced → kernel)
Got my external webcam working now. Not sure why it wasnt working before. However I noticed the billboard device only shows up when I connect my dock. Without the dock this is lsusb. Which one is my webcam? Is it maybe pci?
