problems mounting digital camera

Help needed to mount digital camera. Under Slackware, when I plug in my camera, it is recognised by the kernel, but I can only mount it if I issue the command mount -t usbfs /dev/sda /mnt/camera, whereas under Mdk, it mounts with mount -t vfat /dev/sda /mnt/camera. Now this works under Mdk, and I can see my pics, but I get nothing under Slack except some cryptic directories appearing under /mnt/camera that bear no resemmblance to anything. I have read the digital camera how-to, and am pretty convinced that my camera uses the vfat filing system All that I get under Slack if I try to mount it as vfat is an error saying wrong fs type, or to many mounted devices
Anyone any ideas as to why this is.

did you try with partition number - eg, /dev/sda1 instead of /dev/sda?

are you sure you have the necessary modules loaded - (I'm going from memory....) - uhci, usb_storage. and scsi support?

you didn't mention the model - did you check the LQ HCL for any tips?

Thnx for the fast and accurate reply. Using /dev/sda1 does the trick. I can't say that I understand why, maybe that's something I ned to learn. All I have to do now is get the thing to automount under slack just like it does under Mdk.
Thanks again

good to hear you got it working

sda1 refers to the number 1 partition, whereas sda to the whole device -- not sure why it worked under mdk, might have to do with the automount feature you mentioned....

Dear Genesee and others,

I have to admit I felt a sadistic pleasure finding out others had the same kind of problems I have...

Well, I have almost the same kind of problem that vdemuth had... only in my case changing sda to sda1 didn't work. Here's what I have:

[root@Alex alex]# mount -t usbfs /dev/sda /mnt/camera
[root@Alex alex]# cd /mnt/camera
[root@Alex camera]# ls -l
total 0
dr-xr-xr-x 1 root root 0 Aug 15 22:29 001
dr-xr-xr-x 1 root root 0 Aug 15 22:29 002
-r--r--r-- 1 root root 0 Aug 15 22:29 devices
-r--r--r-- 1 root root 0 Aug 15 22:29 drivers
[root@Alex camera]# mount -t usbfs /dev/sda1 /mnt/camera
mount: /dev/sda1 already mounted or /mnt/camera busy

Something is definitely wrong because I still can't see the pictures, but I can't figure out what... oh yes, -t vfat doesn't help either:
wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems

What can be wrong?

usbfs is a special type of filesystem; it's probably not what you're thinking of. The usbfs is a "fake" filesystem maintained by the kernel to give you information about what devices are connected with USB.

You want to issue a command such as:
mount /dev/sda1 /mnt/camera

You will need to unmount the usbfs filesystem before the previous command will work. It may be simpler for you to just restart the machine to get to a "clean slate".

The information below describes (in very abstract detail) what it is you were seeing with the ls command in /mnt/camera:

The 001 and 002 refer to two different buses (or series of connections if you prefer) that work as USB. Those directories will hold information specific to their bus.

The devices file will contain information about the devices connected on either of the buses mentioned above. It's likely to contain vendor names, product names, etc.

The drivers file will contain information about what modules the kernel is using to talk with the hardware on USB.
