Well, SRM wasn't the problem, then. I was really asking about what Linux saw on the buses, as it is possible that those drivers are sensitive to the termination, and not SRM's drivers (as you already had mentioned that SRM always sees them all in an earlier post). > This is really puzzling though.

Well, I guess there could be a limitation in the number of devices that the installer might create, but the driver probe of the bus OUGHT to indicate all the devices that IT sees, regardless of how many devices the installer creates in /dev. Does Linux always miss the LAST devices that could be created (and is successful on earlier devices on the SAME bus)? If so, that could indicate an installer limitation. --Jay++ --------------------------------------------------------------- Jay A Estabrook HPTC - XC I & B Hewlett-Packard Company - ZKO1-3/D-B.8 (603) 884-0301 110 Spit Brook Road, Nashua NH 03062 [EMAIL PROTECTED] --------------------------------------------------------------- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
