The problem I've is that nothing changed on the machine except that I did a reboot. Nothing (USB device) added, nothing removed, so with a stable hardware config, USB numbering should have stayed stable, IMHO. > > I would have been expecting some more stability in the > numbering across > > reboot, the same way IDE disks numbers are stable. > > Use some other identifier which is stable - e.g., serial number of the > USB device (unfortunately, many devices don't have it). Well yes, I'm going to try to convert to some other identifiers space as this seems to be the only way to go. Thanks for the confirmation, Regards, Paul
