Hello all,
Trying for the first time to download images from a new Nikon D40 camera.
libgphoto2 lists the camera as supported in PTP mode. I have tried using PTP
mode with digikam (hooking up the camera directly), and also simply trying to
mount the memory card using a card reader. Both methods fail.
The card is recognized:

Attempts in PTP mode fail with digikam reporting "Failed to connect to the
camera. Please make sure it is connected properly and turned on". The camera
itself reports that it is connected to the computer properly. When directly
mounting I get:
# mount -t vfat /dev/sdc1 /mnt/camera
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Works on my D40. I haven't tried with digikam though, as I prefer to use
direct file access. I assume that if mounting the card works, PTP should
as well.
I have these lines in my dmesg whenever I try to mount it, or use PTP mode:
Unable to load NLS charset cp437
FAT: codepage cp437 not found
In my kernel config I have this:
(437) Default codepage for FAT
So, is there something else I need to get this codepage? The camera appears to
be detected just fine, and the issue seems to be directly related to mounting
the vfat filesystem and this missing codepage...
Just to note: It is a stable amd64 Gentoo system, and I do have vfat module
loaded when I attempt to mount.
I am on the same arch and have the module fat and vfat loaded. Kernel
version 2.6.23-gentoo-r6.
Any other ideas?
Use an SD card reader, pull your data off, then format the card again?
If you'd like, I can post my kernel config and you can look for
differences between them.
Thanks for consideration,
