On boot and until the event i'm about to describe when i issue a: camcontrol devlist or a cdrecord or the like command the burners are dev 0,0,0 and dev 0,1,0 respectively. Now whenever i insert either my external usb2 hard disk or my 256mb memory stick the devices change buses and id's, maybe going to 3 maybe to 7 or whatever, they change. Through reading and google i believe the fix is to lock the burners to specific device id's in device.hints. I'm not sure how to do this as the examples i've seen reference a scsi controller, the burners use the atapicam driver not a scsi card. In the same context i'd also like to lock down the external devices, so that when they're inserted they'll always have known values. Does anyone have a configuration like this? Thanks. Dave.
