libvirt USB passthrough device fails to connect at guest start

0

I have a desktop setup with

Host:

  • Ubuntu 18.04
  • libvirt 4.0.0
  • linux-4.15 generic

Guest:

  • Windows 10
  • USB keyboard (Corsair K55) in USB passthrough
  • USB mouse in USB passthrough
  • NVidia graphics card in PCI passthrough

Whenever I start the VM, the keyboard remains attached to the host and does not show up on the guest. I have to open the libvirt panel for the VM, remove the entry for the keyboard, and re-add it. At the next VM startup (even without restarting the host), I'm back in the same situation.

Neither my USB mouse nor my previous USB keyboard have this problem. How can I debug the issue?
