This ist not a *media* exchange - this is a *device* and in this case even a scbus exchange. > Please describe how to suppose detect geometry change in this case ?

You won't see the new device as long as the old device blocks the USB event thread. -- B.Walter BWCT http://www.bwct.de [email protected] [email protected] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
