Hi

Has anyone tried this and gotten it right

I am able to get images from the mem stick of a camera by mounting it with the command mount /dev/sda1 /mnt/cam
Note that i dont need to specify the filesystem.

when i issue the command mount it returns that the dev/sda1 is mounted umsdos.

ok so if i copy the pic from the cam to the hard drive all is ok, however if i then copy the same pic back to the cam and then try to view the pic in the lcd on the cam i get a incorrect format error.

ok so i made a loopback dev of the umsdos filesystem and copyed the pic from a folder on the hd to the umsdos filesystem on the hd then, i tried sending the image back to the mem stick using the dd command , but it did not work ( got a format error from the cam again.)

Basically has anyone been able to do this? also the pic that i am using was taken originally with the cam so its not some arb picture that might have a different format.

Just curious
cheers

What USB camera model and what kernel are you using? is mass storage device compiled in the kernel or loaded as a module? did you install libgphoto2 and gphoto2?

and most importent ...when you connect the camera and run "cdrecord -scanbus"
does it show the camera model name correctly?

Note that you CAN'T rename your photos and send them back to the camera ...there is a reason why there called SMS201001.jpeg (in my case)

Your problem is probably that umsdos doesn't allow long file names. Try mounting it as -t vfat instead of letting it guess umsdos. Works for my camera.
