I watched the same summit. It was really good. I’m a fan of the C922 Pro, the quality and field of view is spot on for what I need. It’s very popular, as you know. Thanks for the interest.
Up until a couple of weeks ago I was using an Asus GL553V without an external usb keyboard. When I installed Qubes on this machine, the installer didn’t automatically create a sys-usb qube, and my webcams (both internal and external) weren’t showing up in Qubes Devices, so I manually created a sys-usb qube following the excellent user documentation here: https://www.qubes-os.org/doc/usb-qubes/#qubes-41-how-to-enable-a-usb-keyboard-on-a-separate-usb-controller.
After getting locked out of my computer, I followed this guide https://www.qubes-os.org/doc/autostart-troubleshooting/ to get back in. I then set things up for my mouse and internal keyboard to always pass-through since the Asus apparently just had one (shared) usb bus.
Even with the sys-usb qube, both my internal and external webcams were not still not detected in Qubes devices.
My older Asus with 16GB of RAM wasn’t really getting me where I wanted to go (for my needs) using Qubes as a daily driver, so I decided it was time for an upgrade. I bought a new external mechanical keyboard (with Cherry MX blues) , mouse. and Thinkpad X1 Carbon Gen 9 with an 11th Generation Intel® Core™ i7-1165G7 and 32GB RAM.
Because I had my external keyboard and mouse plugged in when I installed Qubes on my new machine it didn’t create a sys-usb qube again. And again, after installing, there were no webcams detected in Qubes devices.
I thought the qubes-video-companion would be an essential solution after reading this post: I cannot use my (good) Logitech 922 USB Webcam - #8 by Wikinaut, so I downloaded and compiled the RPM from git.
Before I installed everything in dom0, I created a sys-usb qube.
This time I could see both my webcams in Qubes devices, but even after mounting each of them to the destination Qube, they would not stay connected to my video conferencing software for more than a flash of a second. I kept getting a “there is a problem with your webcam” error in cheese and it would eject the mount.
So, I gave it one last go and decided to follow the advice in this post, Unable to connect my Webcam to any AppVM; connects and then fails - #13 by oijawyuh. I increased the initial memory of sys-usb qube from the default setting to 1024 mb in Qubes Manager everything worked!
I’m definitely going to keep an eye out for Qubes Video Manager’s inclusion in a coming update; it looks amazing! However, it turned out to not be a necessary solution for me and my hardware.
I think it would be beneficial if there was something in the install instructions that would educate people about the sys-usb qube, reasons why it might not be auto-created, and how this affects webcams…both internal and external.
Anyway…hope this helps!
