How it is supposed to work?  I'm unable to access my CF (tryed also on
4.8-STABLE w/out success) and after recompiling world (29 march) also
gphoto stopped to work.  Something related to usb device?  I'm missing
something obvious?  Maybe non all CF are msdos formatted/partitioned?

If it can make any difference is a SMP system, with SCHED_4BSD on a
ASUS P2B-DS (dual pIII/500).  I loaded umass0 before connecting device.
CF is from a Canon S30 and I'm unable to access my photos after last
world  :-(
