You need to have usbd running (usbd_enable="YES" in /etc/rc.conf), and
have some options in the kernel:
device scbus # SCSI bus
device pass # SCSI passthrough device
device da # SCSI disk device (for umass)
Maybe doing a '# kldload umass' with a stock GENERIC kernel will also
work, I don't know.
At any rate, when you plug it in, the kernel should discover a new
da device, da0 in my case since I don't have any other SCSI disks:
Jan 1 20:01:26 firsa /kernel: umass0: SanDisk Corporation ImageMate CompactFlash USB,
rev 1.10/0.09, addr 2
Jan 1 20:01:26 firsa /kernel: umass0: Get Max Lun not supported (STALLED)
Jan 1 20:01:27 firsa /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Jan 1 20:01:27 firsa /kernel: da0: <SanDisk ImageMate II 1.30> Removable Direct
Access SCSI-2 device
Jan 1 20:01:27 firsa /kernel: da0: 650KB/s transfers
Jan 1 20:01:27 firsa /kernel: da0: 122MB (250881 512 byte sectors: 64H 32S/T 122C)
I was then able to do something like
# mount -t msdos /dev/da0s1 /foo
To access the data. Note that my CF has partitions (?!) which took me a while
to figure out. It may be that your camera doesn't need that in which case
you need to do 'mount /dev/da0 /foo' of course.
Note that I have a card reader in which I plug my compact flash card;
some digital cameras don't have umass access but need their own protocol,
for which gphoto is likely to have support (as another poster alread said).
