hostowner, after /dev/hostowner, and eve, after the kernel
variable name, refer to the same thing.  eve is "" until set
by factotum -S (cpuserver) or factotum -u (terminal).  factotum
writes the hostowner to /dev/hostower and as a special case
the setting process' owner is reset as well.

with the default install, a cpu server's hostowner is bootes.

auth/debug is always a good start.  no arguments, no man
page.  just run it.

once that fails, i'd use acid(1) truss to pinpoint the system
call that results in permission denied.  if it is /dev/usb*,
i would use scuzz(8) to double-check that it isn't a bug or misleading
message in devusb.  giving scuzz the "probe" command should
list all the available sd devices.  if it does not, then it's likely
a real permissions problem.

it's pretty likely that i haven't foreseen what's really going
wrong on your system.  so you're probablly going to need
to do a bit of experimentation.

good luck.
