But I think it fails this time because you've updated to debian testing and, correct me if I'm wrong, but the udev utility cdrom_id came with the update and it sends all those GET_CONFIGURATION commands. Have you thought of updating the drive's firmware - that helps sometimes? -- Regards/Gruss, Boris. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
