When running qemu with -device usb-host an assertion failed caused by attaching a new usb device to the host that gets routed to the guest.
The assertion that fails is: qemu-system-x86_64: /home/erik/qemu/hw/usb.c:358 usb_packet_complete: Assertion 'p->state == USB_PACKET_QUEUED' failed. It was working with the master ~1-2 weeks ago. Best regards, Erik
