The easiest way I see is to attach a "ugen" device with high
priority - something like
ugen0 at uhub4 port 7 flags 1

But I'd like to understand why the kernel thinks that
the virtual USB disk is the device it booted from.
It should try to match information passed by the
bootloader to the disks probed, and this worked well
so far.
How are you booting that box?
