If you open e.g. /dev/cam or /dev/scg?, you open device that is not related to a high level service like /dev/hd* and this unfortunately is unable to talk to other devices in the same entity (e.g. ATAPI tapes). With /dev/cam or similar you get a single handle for a group of devices that than are addressed via something very similar to dev=b,t,l J?rg -- EMail:joerg@schily.isdn.cs.tu-berlin.de (home) J?rg Schilling D-13353 Berlin js@cs.tu-berlin.de (uni) schilling@fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.berlios.de/old/private/ ftp://ftp.berlios.de/pub/schily - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
