usbfs is not mounting the camera, hence the odd files you see.

It seems that this camera is simply not recognised by the usb-storage module. I think you may be SOL.

Keep the vfat or auto option but try changing /dev/sda1 i.e. /dev/sda2 and do you use root to mount.

Changing the partition number won't help if fdisk says there are no partitions on the device.

I have tried different partitions, even just /dev/sda. The trouble is it just will not mount using vfat.

Then it's not mounting with anything. ignore usbfs, it will mount the same thing whatever device you give it, existing or not. If you need convincing, try
Code: Select all
mount /dev/someloadofoldrubbish /camera -t usbfs
ls -l /camera


Does /dev/sda1 even exist? What does "ls -l /dev/sd*" show?

brw-rw---- 1 root   disk   8,     9 Dec  3 2004  /dev/sda9


Hmm, I think I mentioned there was no sda1 before... but anyway, it isn't there!

When I change the fstab entry to, say, /dev/sda2 I get th eerror message:
Code: Select all
/dev/hda2 is not a valid block device


I think we may be getting to the root (no pun intended...) :roll: of it.

Don't mount as /dev/sda1
but mount as /mnt/whatever

I do, I use mount /camera
and yes, I have swapped the USB port used.

I think the issue is with the 'missing' sda1, maybe?

It's a kludge, but what happens if you create /dev/sda1 manually?

Code: Select all
mknod /dev/sda1 b 8 1

I have just installed Ubuntu on the main PC now, I will try that later. Failing that, I'm afraid it's back to Windows 2000. I need my wife and kids to be able to just plug the camera in and use it, so far there is just too much p!ssing around...

:~$ mount /camera This command could be wrong if your mount point was in your home dir it would be
mount /home/whatever/camera or if it was in mnt directorty it would be mount /mnt/camera

I think we have established that it is the device node, not the mount point, that is the problem.

I doubt this has any bearing, but are you using udev or devfs?
