The goal: mount my new Canon Rebel 300D to linux directly via USB

The problem: i have no device /dev/sda1 to mount to

mounting the drive is not a problem. i can figure that out. i've got my fstab all set up and ready to go for it. but there is no drive to mount. all the other camera/USB threads and tutorials talk about how to load modules and add /dev/sda1 to your fstab, yada yada yada, but i don't *have* /dev/sda1. So, where does it come from and how do i get mine? I know it's a SCSI device, but i've also got a CD Writer installed and working, so i know that the SCSI system is working to an extent. I also know USB works basically. Can anyone help or tell me where /dev/sda1 comes from? Am i going to have to recompile my kernel? (noooo!!!)

------------------------------------------

tail -f /var/log/messages outputs the following when plugging in and turning on my camera:

------------------------------------------------------

it seems the key is that "USB device 5 (vend/prod 0x4a9/0x3084) is not claimed by any active driver."

any thoughts?

Susan Macchia wrote a very nice item in March 2003 on "Using Multi-Card Flash Readers" - For your suggestion, the ideas on the sg utils ( http://www.torque.net/sg/index.html#...nd%20sg3_utils ) could help you find out who is doing what where.

Multi-card just means mounting 4 sub devices rather than one main (I think) so the same general precepts should apply

It does appear that you have the proper modules loaded.

cdrecord -scanbus
will tell you what bus the device is on

I don't know if you need to enter command like
echo "scsi add-single-device 0 0 0 0" > /proc/scsi/scsi
but it sounds reasonable. I wish I new more about why, though.

sg_scan -i
Will tell what devices are on scsi, they should match whats in /proc/scsi/scsi.

sg_map
Shows the mappings of devices. This will help you figure out which device name to use when mounting.

I save the doc and not the link but you should be able to find it with a net search. - Linux Step by Step I think.

It really gets confusing when I try to mount the 6 in 1 reader and an external usb drive in different orders and then try to figure out who mounts where. I have a lot to learn.

sg_can and sg_map are not recognised on my system.

-----------------------------------

usbview shows that a "Canon Digital Camera" is connected to the root hub when it gets turned on.

-----------------------------------

lsusb outputs:

Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 002 Device 021: ID 04a9:3084 Canon Inc.
Bus 001 Device 001: ID 0000:0000

so it does pick it up

------------------------------------

i'm not sure where it came from, but i also seem to have a /dev/scd1 which points to

/dev/scsi/host1/bus0/target0/lun0/generic

trying to mount it to /mnt/cam outputs:

mount: no medium found

------------------------------------

a similar output comes from cdrecord -scanbus

BUT THERE IS A COMPACT FLASH CARD IN THE CAMERA. i did the same thing with a lexar usb flash card reader - same thing - it says it's not there. i tried to format the card in the camera and on the computer as well. still says it is not present.

--------------------------------------

any other thoughts? this is very frustrating.

that is why I provided a link to where you can find them.

It is a diagnostic utility and may or may not help depending upon how much diagnosing you are into and whether you can figure out what the output is saying.

I often find trying to mount by trial and error is a way to relive frustration and maybe hit gold.

Assuming /mnt/temp exists as a directory and is currently unattached,

mount /dev/sda1 /mnt/temp

work? no, got error messages

mount /dev/sdb1 /mnt/temp

work? no

mount /dev/sdc1 /mnt/temp

etc. What works often depends upon what port the device is plugged into.

sometimes I feel like one of those monkeys involved in typing the Bible when it comes to figuring out linux hassles.

i've figured out that Mandrake 9.1 will *create* /dev/sda1 when it sees a USB card reader plugged in. It also dynamcially creates /mnt/removable in fstab at the same time.

however, if i plug the camera in directly, it does not recognise it as a mass-storage device. pehaps it is because the camera is brand new (just released last week).

so... is there any way to get it to recognise my particular camera as a mass storage device?

Forgive me if I am spouting incorrect info, but I have generally found the following to be the case: Either your camera shows up as a mass storage device (like my sony dcr-pc9) or you have to use the digital camera tools to "extract" the images from it.

If you are like me it can be used as a storage device, but I have to mount the /dev/sda1 as -t vfat after kudzu mounts it as fat. I have other problems with camera's and mass storage devices in linux, but that is for another thread.

leiavoia: this maybe helpfull:
http://www.linuxquestions.org/questi...hreadid=130254

hey.

i've got a no name digital camera. i believe it's on the scsi; i've found it buried deep in the directory.

i tried to mount it to /mnt/camera using mount -t vfat ./<name> /mnt/camera, and this is the message it gives me:

wrong fs type, bad option, bad superblock on <name>, or too many mounted file systems.


i'm pretty sure the thing is on ./<name> because when i unplug the camera and try the mount command, it tells me that it cannot find the device.

i'm wondering if there's a way to probe the fs type.

I don't think it's a filesystem problem...

These kind of errors crop up when all the scsi services are not completely installed in the system. My guess is that you need to install more of the scsi emulation libraries to get the thing to recognize.

Also, many cameras have the ability to switch them from scsi emulation mass storage device to a PTP camera device. If your camera is set to be a PTP device then you probably won't be able to pull the images off it like it was a scsi device. However, the scsi emulation might want to make the camera out to be a mass storage device...

where do i get these SCSI emulation libraries?

I have a Canon A80 - like another poster said, cameras don't necessarily turn up as storage devices - and my Canon doesn't, so maybe yours is the same. For non storage accessible cameras you have to use utils like gphoto2:
http://www.gphoto.org/
GUI interfaces to gphoto2 are available, and it also integrates into Konqueror:
http://www.thekompany.com/projects/gphoto/

BTW - the normal unenhanced konqueror also knows how to get at the EXIF data tags commonly found in digital photos - just hover over an image

They should come with your distro...
