For your comparison here a screenshot with the devices passed through. I did -not- hit the issues you had which is good for me but bad for helping you. I'd think that you can avoid: Warning: speed mismatch trying to attach usb device "Porsche Desktop" (super speed) to bus "usb.0", port "1" (full+high speed) By setting the USB controller to a USB 3.0 type.
But I wonder why you still get issues accessing the device at all. qemu-system-x86_64: -device usb-host,hostbus=2,hostaddr=2,id=hostdev0,bus=usb.0,port=1: failed to open host usb device My guest log shows nothing like that :-/ But give the USB 3 controller a try on your side, it will help a bit even though I can't promise how much. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815588 Title: speed mismatch trying to attach usb device to guest vm To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1815588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
