SCSI/Digital Camera Question

Jiawen · 10-05-2003, 12:23 PM

I'm trying to read pictures from my Casio QV-2900X camera through a USB port. I'm using Mandrake 9.1. Can you help?

I found <http://www.harald-schreiber.de/>, which seems to address my questions pretty directly. However, towards the bottom of the page, he says

Quote:

If you have no SCSI disks in your computer system you can access the storage of your camera as /dev/sda1. If you have one SCSI disk you can access the storage as /dev/sdb1, and so on. In the following let's assume that you have one SCSI disk in your system and so you access the storage as /dev/sdb1. To create a mount point for your camera you have to type:

mkdir -p /media/camera

then append the following line to the file /etc/fstab :

/dev/sdb1 /media/camera vfat ro,noauto,user 0 0

Now every user can mount the storage of the camera by typing mount /media/camera. Be sure to type umount /media/camera before you disconnect your camera.

I have several questions about this:

1. How do I know how many SCSI drives I have mounted? I have two physical hard drives in this computer -- does that mean the camera would mount at /dev/sdc1?

2. Is it safe to edit /etc/fstab as he says?

3. Has anyone else had success mounting this camera? I could always just mount it on my other (Win2000) computer, but I'd rather get it working on my Linux system.

I know my questions are pretty obvious, but please help anyway!

Thanks in advance for any help you can give.

Do you have a scsi hardrive or not?
These are known as /dev/sd*

Is it IDE ?
These are known as /dev/hd*

Don't get confused here. USB uses the SCSI interface to use in the computer. Basically it means why write a new interface when half the work is already done.

If it is ide then the most likely start is /dev/sda1. This means device sda with parttion 1.

As long as ' lsmod ' list usb modules that are loaded. Just plug in your camera and use this mount command ' mount -t vfat /dev/sda1 /mnt/camera '.

Hope this helps

Thanks for the fast response!

How do I know if I have IDE or SCSI drives or not? I bought them so long ago, I don't remember which I had. When I go into /dev/, there are 5730 (!) items there, and there are tons of /sd* and /hd* items. Which ones are which?

Actually, I just thought to check KDiskFree, which lists my drives as /dev/hda1, /dev/hdb1, /dev/hdb5. /dev/hdb6 and /dev/hdb8. Does that mean that they're all IDE-type drives? Where is the camera, then? /dev/sda1?

Do I need to plug the camera into the USB port and then type "mount -t vfat /dev/sda1 /mnt/camera," or type that and then plug in the camera?

And sorry to be such a newbie, but what did you mean by "As long as ' lsmod ' list usb modules that are loaded."? How do I know if those modules are loaded?

Again, thanks in advance for any help.

Your drives are all IDE.
Plug the camera into the PC and then mount it.

If Mandrake detected the USB controller it will already configured with the modules loades.

If your camera shows up as a usb mass storage device, this might be useful:

Oh, yes, I got it! It works! Yippee!

I did the whole mount /dev/sda1 /media/camera thing, then modified /etc/fstab, and I can now mount and unmount and read photos and the whole thing. Now I just need to remember to turn the camera on before I plug in the USB cale -- not as obvious as it sounds, because plugging in the cable automatically turns it on, but it also automatically turns itself off very quickly, and I need to make sure it's on long enough to read the photos.

Now, I need to buy a bigger hard drive.

Thanks for all the help, everyone who helped.
