[-- Attachment #1 --] (please include my and Dan's email in any responses as we normally don't lurk on the USB mailing list) So @work we use serial->USB TTY MUX's to handle our serial console needs, and at some sites we have a need that is greater than a single 16 port device (the max you can get). The problem is that with two of these 16 port USB devices is that sometimes during a reboot that the "second" device gets probed first and so the first 16 and second 16 /dev/ttyU* blocks swap around... which of course plays havoc with any symlinks we have to the devices in rtty or conserver. :( Is there any way to tell the USB code to always select a certain device first? I assume this has been a issue with USB storage devices so this shouldn't be a new issue. And I tried searching for a answer on the web to no avail. Ideas?
