Gphoto documentation states Nikon d70 as a ptp mode camera. ptpcam 
states that, as well.

If I use the usb mass storage option, I get lines like these on my 
dmesg, whe I turn the camera on:

Buffer I/O error on device sdb1, logical block 2001445
Buffer I/O error on device sdb1, logical block 2001446
Buffer I/O error on device sdb1, logical block 2001455
end_request: I/O error, dev sdb, sector 2001487
Buffer I/O error on device sdb1, logical block 2001424
Buffer I/O error on device sdb1, logical block 2001425
Buffer I/O error on device sdb1, logical block 2001426

If I insist and try to mount it, I get:

frank:/home/bruno# mount /dev/sdb1 /media/usb1
mount: you must specify the filesystem type
frank:/home/bruno# mount -t vfat /dev/sdb1 /media/usb1
mount: /dev/sdb1: can't read superblock

If I use the ptp mode instead, both gphoto and ptpcam can see the camera 
and download files.
The only explanation is D70 being differently detected than D70s, which 
I find odd.

Anyway, ptp mode s doing well now. I'd only like to access it in a 
non-root account.
