USB error: vendor cannot be 0

[ToddAndMargo]

Hi All,

Anyone know a work around for this?

   Fedroa 32, x64

   $ rpm -qa virt-manager
   virt-manager-3.1.0-1.fc32.noarch

   $ rpm -qa qemu-device-usb-redirect
   qemu-device-usb-redirect-5.1.0-7.fc32.x86_64

Bug I filed on 2020-06-23:
   libvirt.libvirtError: internal error: vendor cannot be 0.
   https://bugzilla.redhat.com/show_bug.cgi?id=1850091

I am trying to install a USB Host device for my
Samsung BAR flash drive and I get the following error:

   Unable to add device: internal error: vendor cannot be 0.

Many thanks,
-T
