Check the settings of sys-usb and verify the Devices tab shows both USB controllers assigned.
No. Only one.
I added the second, and now I cannot use my Qubes system any more —> as it does not accept my password or any keyboard input!
Pls. assist.
Help is needed. I cannot access my Qubes after booting and after successfully unlocking the disk.
The USB keyboard is apparently now not connected any more to the dom0.
How to fix that?
basically, I am HERE:
Can’t use keyboard or mouse after creating sys-usb
You risk locking yourself out of your computer if you have a USB keyboard and use full disk encryption alongside sys-usb. On boot, the keyboard may be inactive, preventing you from entering your LUKS decryption password.
I can unlock my disk but I cannot enter characters to the user login screen.
pls. assist.
Did you actually read the page referred to in the thread?
Do you use uefi or legacy boot?
This has come up quite recently in the forum: look for “locked USB
keyboard” or similar
UEFI Boot.
Oops, sorry that happened, that’s why I indicated not to reboot, but I suppose you have a separate issue that qubesctl doesn’t handle - sys-usb not booting.
-
Do you see any errors at boot indicating an issue with sys-usb starting? You may have to hit escape after typing your disk password.
-
What template do you have for your “default template”? Is it a minimal template, not Fedora, or not Debian?
I suspect your sys-usb qube isn’t starting, doesn’t have qubes-input-proxy-sender installed, or has some other unknown issue.
If that is the case, reboot and append the following to the kernel command line:
qubes.skip_autostart
If you’re booting with UEFI, you’ll have to use a LiveCD to boot, then edit your EFI System Partition’s /EFI/qubes/xen.cfg file. (example)
This should let dom0 keep ownership of the controller and allow login using the USB keyboard. If you’re able to login, then disable auto start of sys-usb using the sys-usb settings, and you can re-edit (as root) /boot/efi/EFI/qubes/xen.cfg and remove qubes.skip_autostart.

Many thanks.
Will apply the mentioned steps some hours later.
So. Now I have my Qubes up and running again, thanks.
What can I do to get the LOGITECH 922 Webcam working, are there any ideas left?
Hello @noti2p, is there anything you can recommend to me to try to get the webcam working with Qubes?
Hello dear all, is there now anything left, I mean, is there any further proposal how to overcome the problem of not being able to use my USB Logitech Webcam with Qubes on my Intel NUC computer?
@Wikinaut did you ever get around to trying a HWM with one of your USB controllers assigned to it (not the one with keyboard/mouse!)? That’s the closest you could get to a native Linux install and it usually works.
The other option would be to try the R4.1 Alpha of Qubes (dom0 is based on a much newer version of Fedora)
Is there a way to upgrade to that R4.1 Alpha version?
Is there a way to upgrade to that R4.1 Alpha version?
Nope. Needs to be a fresh install. But you could backup/restore your qubes.
I installed that version. Same. I do not see the USB Webcam. I now also tried a simple USB Headphone (Sennheiser PC25) with integrated USB soundcard → this is also not detected as USB.
Only USB memory sticks are detected as usual.
My original comments from I cannot use my (good) Logitech 922 USB Webcam still stand.
You run into an issue where sys-usb did not get created properly or did not have the input proxy configured. We have to figure this out first.
dom0 will not be able to utilize your web cam - you must have a working sys-usb, which is compounded since you have one USB controller and are using a USB Keyboard.
I installed Qubes 4.0.3 on a different computer (FUJITSU), also again with my USB-mouse and USB-keyboard and again, there is no USB-WEBCAM available. I am giving up now.
I’m facing exactly the same problem as @Wikinaut. I don’t think it is trivial to fix without Linux kernel and usbip expertise. What is going on is something like this:

Behavior is as follows, when camera is initially connected to VM it is visible:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 011: ID b58e:9e84 Blue Microphones Yeti Stereo Microphone
Bus 001 Device 017: ID 046d:085c Logitech, Inc. C922 Pro Stream Webcam
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
But if anything “touches it” it disappears despite being visible sys-usb menu as connected to VM.
What is needed is debugging of vhci_hcd driver it other parts of usbip subsystem. The error may come from here.
Did you find a fix?
I’m having the same trouble with Logitech C920. If I run “cheese” on VM that has the USB controller, it works flawlessly. But if I attach the camera to another appvm, cheese and other applications become very unstable. Sometimes it works, sometimes not, but definitely not many times. I need to detach/attach, possibly multiple times, and then it might work.
Same error messages, “Not yet implemented” etc.
Here’s a long github issue about it: Cannot use a USB camera · Issue #4035 · QubesOS/qubes-issues · GitHub
But I cannot read from the issue if it’s fixed or is the problem even known, or is anyone interested in it.
No, it is not solved. I gave up using Qubes.
Sad to hear 
If one day you could take the time to write a post about what failed for you (apart from this issue), I think could be great feedback to make the project better. So hopefully one day you can try it again and those issues will be gone. But only if want to, of course.
