LVM should look at all of the devices.

Most likely the firewire interface/driver takes longer to startup than the
USB does, and the drive isn't visible when the startup scripts do their
vgscan.

You might scan through their startup scripts and figure out where they do
this.  I've seen startup scripts that do wait for USB devices to settle,
and perhaps they need to be enhanced to wait for firewire to be present.
