I recently upgraded my laptop from Leap 15.4 to 15.5. After that i can no longer assign USB devices to a guest system. I tried my iPhone and a USB memory stick. Both fail in the same way: the device doesn’t get checked in the devices list and after the try i can still see the device on the host system. Nothing happens on the guest system.

Here a snap of the hosts /var/log/messages file when i try to assign a USB stick to a Linux guest (both host and guest run Leap 15.5)

# tail -f /var/log/messages

On the guest i have:

# rpm -qa | grep -i virtualbox

virtualbox-kmp-default-7.0.8_k5.14.21_150500.53-lp155.1.6.x86_64

Likely unrelated problem i also have after the upgrade, but i’ll just mention it: KDE can not shutdown my laptop. Instead it reboots it. I can power it off with ‘systemctl poweroff’ though.

    the 5.14.21-150500.55.22.1 kernel is bad use the 5.14.21-150500.55.19.1 kernel.
    Something got built wrong but got past QA.

Indeed going back to 5.14.21-150500.55.19.1  resolved my issue. larryr asked me to file a bug, so here it is....
