> VM configuration using Conbee II as a USB device.

Could you please help to capture the trace data and upload it?

1. Make sure the vm USB_Test is off.
2. On host, issues below commands as a priviledged user:
lsusb -t
virsh start USB_Test --paused
virsh qemu-monitor-command USB_Test --hmp "trace-event usb_host_claim_interface
on"
virsh resume USB_Test
lsusb -t

Then upload the outputs of the two lsusb commands and the
/var/log/libvirt/qemu/USB_Test.log

TIA
