Hi Eero sorry that you are still affected by issues on your usb passthrough. But I read that at least the upgrade got you further for bug 1814061.

I need to grab some HW from my basement after lunch for a test - stay tuned ... :-) -- 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
