Stephen suggests:
What is in your log files when you load the driver? DO you have scsi disk and generic in your kernel?
Ok, I just re-compiled the kernel. Previously I had the following as modules, now they are included:
SCSI device support
SCSI disk support
SCSI generic support
USB Mass Storage support
Also previously I had not inserted scsi disk or generic support when I tried to mount the camera.
Now mount reports the following error:
mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systemsThe last lines of dmesg are: FAT: bogus number of reserved sectors VFS: Can't find a valid FAT filesystem on dev sda. which suggests the problem is a wrong fs type.
I also get a kernel bug at boot-up. The full text is in the output of dmesg (at the end of the message); here is a summary:
Adding 1534196k swap on /dev/hda3. Priority:-1 extents:1
kmem_cache_create: duplicate cache sgpool-8
------------[ cut here ]------------
kernel BUG at mm/slab.c:1268!
invalid operand: 0000 [#1]
I am compliling using Gcc 3.2.2, which is a no-no, but have not had problems previously.
Thank you again for your help & suggestions!
