Could you give the detail qemu cmdline about usb-bot?

No cdrom.
My patch is to solve this problem, usb cdrom emulated as cdrom.
This is a libvirt bug, it should use usb-bot instead of usb-storage
together with -blockdev. Then it can add a scsi-cd device below usb-bot.

The drive interface supports media=cdrom so that the usb cdrom
can be emulated as cdrom in qemu, but libvirt deprived the drive
interface, so media=cdrom is added to the blockdev interface to
support usb cdrom emulated as cdrom

What problem are you trying to solve?
