You should try to mount your camera manually first as
mount_msdosfs /dev/ugen0 /mnt
If you can not read the camera only then you should use gphoto2 but
logged as a supper user to avoid
permission problems. If that fails i.e. if you get the message BLOCK
DEVICE RECUIRED you
should try to use gphoto2.
This is step by step for my Sony Cyber-Shot W70
1. Change into PTP mode on camera
2. Go to su mode (this can be avoided but I left it so that my wife
cannot mess with it)
3. gphoto2 --auto-detect will list your camera as Sony DSC-F707V (PTP
4. gphoto2 --help to get various commands
5 gphoto2 --L will list all the files in numerical order
6 gphoto2 --get-file=NUMBER Range (will get you files in that range)
7 WARNING you may need to issue the commands some time multiple times
they fail. The following message is not uncommon
*** Error ***
Note you might not need to go to PTP mode for your particular camera!
If that fail then you can use cheap card reader which are well detected
There is an excellent thread that you can review
maybe somebody left specific details for you camera but I think I gave
you a big push:-)
Please let me know how it goes.
