I have an old digital camera which has a 64MB CF card in it. A friend
loaned me a USB card reader to extract the images.  I don't seem to be
able to mount it on FreeBSD-4.7-STABLE per the umass man page.

After plugging in the card and USB reader, dmesg shows:

  umass0: PQI Travel Flash, rev 1.10/2.05, addr 2
  da1 at umass-sim0 bus 0 target 0 lun 0
  da1: <General Flash Disk Drive 2.05> Removable Direct Access SCSI-2 device 
  da1: 650KB/s transfers
  da1: 62MB (126976 512 byte sectors: 64H 32S/T 62C)

The man page says:

           camcontrol rescan 0

     Rescan a Zip drive that was added after boot.  The command above assumes
     that the Zip drive is the first SCSI bus in the system.

           disklabel -w -r da0 zip100
           newfs da0c
           mount -t ufs /dev/da0c /mnt

I do the camcontrol and it appears to see it:

  thanatos# camcontrol rescan 0
  Re-scan of bus 0 was successful
  thanatos# camcontrol devlist -v
  scbus0 on ahc0 bus 0:
  <SEAGATE ST19171W 0024>            at scbus0 target 0 lun 0 (pass0,da0)
  <  >                               at scbus0 target -1 lun -1 ()
  scbus1 on umass-sim0 bus 0:
  <General Flash Disk Drive 2.05>    at scbus1 target 0 lun 0 (da1,pass1)
  scbus-1 on xpt0 bus 0:
  <  >                               at scbus-1 target -1 lun -1 (xpt0)

I skip the disklabel and newfs since I've got photos on it already.
Attempts to mount fail:

  thanatos# mount -t ufs /dev/da1c /mnt
  mount: /dev/da1c on /mnt: incorrect super block
  thanatos# mount -t msdos /dev/da1c /mnt
  msdos: /dev/da1c: Invalid argument

Any clues? Thanks.
