The trigger in udev should have done that when dev was removed.  Did you
have UDEV_INITRD changed from its default to "no"?  That'd break your
box at reboot (not starting udev early implies that you can depend on
/dev being there, and it's gone), and then it's time to find a rescue
disk.

Historically, I wasn't been able to attach to the device until the
PDA was attempting to sync.  When you press the sync button, does udev
create the device nodes?  If not, then there's a bug somewhere.

That's a "MAKEDEV-and-udev disagree on permissions" thing.  There are
probably going to be others -- please file this as a bug against either
MAKEDEV or udev.  At some point maybe I should wrestle a udev person for
the right to decide, and take a dive.
