virt-manager windows 10 guest usb passthrough logitech brio webcam

in flag

here is my setup:

  • host: ubuntu 21.04
  • libvirt: v7.0.0
  • guest: windows 10 pro N (version 21H1, OS build 19043.1083)

i am trying to connect my logitech brio webcam to the guest machine. i set up the machine using virt-manager

what i have tried:

  • connect to the host machine via usb 3.1 port
  • i also have a usb splitter attached to the other 3.1 port that holds the keyboard, mouse and mic inputs
  • virt-manager --> info --> add hardware --> USB host device --> logitech brio (002:004)
  • i have tried this while the guest is running, rebooting, and adding it while off before booting it up - none of them had any effect
  • i also saw this thread which advised removing unused devices which also did not help (i removed tablet and optical drive)

what happened:

  • windows detects the device and installs drivers
  • in device manager it shows logitech brio webcam and says it is functioning normally with the latest drivers
  • in the windows camera app it detects the camera (and initiates the webcam light indicating it is in use) but the preview window is all black
  • when taking a picture: error code 0xA00F4292<PhotoCaptureStartTimeout>
  • when recording a video: it seems to record (preview is still black)
  • when playing back the video: Error Unsupported video type or invalid file path

any advice on how to proceed? i need to use the VM for work to run windows-only camera software.

It may be a bit late, but I have created a bug ticket on Qemu that addresses your issue: https://gitlab.com/qemu-project/qemu/-/issues/1613

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
