This article is about how you can use digital cameras that have a USB connection with Linux. There are two types of digital cameras: [[USB mass storage device class|mass storage cameras]] and [http://en.wikipedia.org/wiki/Picture_Transfer_Protocol PTP] cameras. With mass storage devices you connect the camera via USB and can read the photographs as if the camera was a USB hard disk. With PTP cameras, you need software to read the pictures. On most cameras, you can switch if you want to use them as PTP or mass storage cameras. In both cases, you can pull out the storage chip and use it in e.g. and SD-card-reader which will behave like a USB disk. This article uses SUSE Linux 11.1 as example, but it should work same or similar on every Linux distribution.
 
 
 
= Choosing a digital camera =
 
* does it have a menu structure that you understand?
 
* what resolution has it (MegaPixel)?
 
* can you use SD cards (many computers have slots for them)?
 
* is it capable to use SDHC cards?
 
* can you charge it using a standard adapter (micro USB)?
 
* do you want it to be watertight?
 
 
 
Thanks for the a new challenge you have unorevced in your blog post. One thing I would really like to discuss is that FSBO associations are built after a while. By introducing yourself to the owners the first saturday their FSBO can be announced, prior to the masses begin calling on Wednesday, you create a good interconnection. By sending them tools, educational components, free accounts, and forms, you become a great ally. By using a personal interest in them in addition to their scenario, you develop a solid connection that, many times, pays off in the event the owners decide to go with an adviser they know along with trust  preferably you.
 
 
 
= Mass storage cameras =
 
Make sure your system log is empty. [[open a console]] and type
 
dmesg -c
 
Now switch on and connect your camera to a USB port. Then type
 
dmesg
 
At the end of dmesg you should see something like
 
usb 8-3: new high speed USB device using ehci_hcd and address 3
 
usb 8-3: configuration #1 chosen from 1 choice
 
scsi5 : SCSI emulation for USB Mass Storage devices
 
usb-storage: device found at 3
 
usb-storage: waiting for device to settle before scanning
 
usb 8-3: New USB device found, idVendor=054c, idProduct=0010
 
usb 8-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
 
usb 8-3: Product: Sony DSC
 
usb 8-3: Manufacturer: Sony
 
scsi 5:0:0:0: Direct-Access    Sony    Sony DSC        6.00 PQ: 0 ANSI: 0 CCS
 
sd 5:0:0:0: [sdc] 1953792 512-byte hardware sectors: (1000MB/954MiB)
 
sd 5:0:0:0: [sdc] Write Protect is off
 
sd 5:0:0:0: [sdc] Mode Sense: 00 00 00 00
 
sd 5:0:0:0: [sdc] Assuming drive cache: write through
 
sd 5:0:0:0: [sdc] 1953792 512-byte hardware sectors: (1000MB/954MiB)
 
sd 5:0:0:0: [sdc] Write Protect is off
 
sd 5:0:0:0: [sdc] Mode Sense: 00 00 00 00
 
sd 5:0:0:0: [sdc] Assuming drive cache: write through
 
  '''''sdc: sdc1'''''
 
sd 5:0:0:0: [sdc] Attached SCSI removable disk
 
sd 5:0:0:0: Attached scsi generic sg4 type 0
 
usb-storage: device scan complete
 
That means your camera's pictures are available on device ''/dev/sdc1''. If you are flooded by dmesg's messages, you can also look at it using
 
# [[hwinfo]] --block --short
 
disk:
 
  /dev/sda            SAMSUNG HD103UJ
 
  /dev/sdb            WDC WD3200AAKS-7
 
  /dev/sdc            Sony DSC
 
partition:
 
  /dev/sda1            Partition
 
  /dev/sdb1            Partition
 
  /dev/sdb2            Partition
 
  /dev/sdc1            Partition
 
cdrom:
 
  /dev/sr0            HL-DT-ST DVD-ROM GDRH20N
 
  /dev/sr1            TSSTcorp DVD+-RW TS-H653B
 
You can now mount ''/dev/sdc1'' to /mnt/camera:
 
sudo mkdir -p /mnt/camera
 
sudo mount ''/dev/sdc1'' /mnt/camera
 
Now you can find your pictures and movies on /mnt/camera.
 
 
 
= PTP cameras =
 
If you have a PTP USB digital camera, you can get all its pictures transferred with gphoto2. So [[build and install gphoto2]], then [[open a console]] and type
 
mkdir photos
 
cd photos
 
gphoto2 --get-all-files
 
 
 
= TroubleShooting =
 
 
 
'''Symptom:''' When trying to mount your camera, you get
 
mount: unknown filesystem type 'vfat'
 
 
 
'''Reason:''' Your kernel does not have vfat support compiled in nor does it have vfat compiled as a module. The following shows how it should look like:
 
 
 
# cat /proc/filesystems | grep vfat
 
        vfat
 
# lsmod | grep vfat
 
vfat                  11752  1
 
fat                    53592  1 vfat
 
# zcat /proc/config.gz | grep -i fat
 
# DOS/FAT/NT Filesystems
 
CONFIG_FAT_FS=m
 
CONFIG_VFAT_FS=m
 
CONFIG_FAT_DEFAULT_CODEPAGE=437
 
CONFIG_FAT_DEFAULT_IOCHARSET="iso8859-1"
 
 
 
'''Solution:''' Install a kernel with vfat support, best use the one from your distribution. SUSE Linux 11.1 is known to work.
