I think some usb cd devices might just pretend to be disks. When I wrote the original usb mass storage driver (ca 2005) I had only flash drives in mind. Others have extended and rewritten it many times since, to handle more varied and variously cranky devices, but that original hidden assumption has been lurking ever since, waiting to bite you... sorry.
