Re[2]: Working backwards from a BSDname to service

What is "myBSDName" is it "disk3"? "/dev/disk3"?

OUCH! I apologize. The bsdname is as in 'disk3s12s2'

I'm not sure if you've gotten a clear enough pointer in the right direction so I'll offer a tip or two. First question if where did you get the dev node from? Do you already have it mapped to IOService, or do you just have a dev node string?

If you don't have an io_object, you need to get one. Not sure what the "best approach is". It's pretty easy to get an ioiterator on the whole registry and go through the whole thing looking for that property (that's what I did when I needed to do this), but I'm not sure it's the "best" way. Some one else should comment on that.

Once you have a reg object, you can use the technique Garth pointed to. Alternatively, since you control the driver your looking for, you can add a property to you driver and search for that property using
"IORegistryEntrySearchCFProperty".
