spice_usb_device_manager_get() can fail, for instance if usbredir
is not enabled at compile time. You can pass a GError** instead
of NULL to warn user about the fact that its cd-rom will not
show up in the guest for whatever reason it might be.
Just switch to the local get_usb_device_manager_for_option()
added in the last commit
