Hi, Jeff,
Yes, I did put 502 here. That's the typo in my last
email. Sorry about that.
Here is a segment of my fstab information:
...
none /proc proc defaults 0 0
none /proc/bus/usb usbfs devuid=0,devgid=502,de
vmode=0660 0 0
...
whatever I comment out the first line or not, the
result is the same. There is no any error output after
I follow whatever the step you showed me.
But there are some error output when I issue the
gphoto2 command with option under a non-root username,
like reno.
The error output followed:
$ gphoto2 --list-files //first time
Segmentation fault
$ gphoto2 --list-files //second time
*** Error ***
PTP Protocol error, data expected
*** Error ***
An error occurred in the io-library ('Unspecified
error'): The supplied vendor or product id (0x0,0x0)
is not valid.
*** Error ('Unspecified error') ***
For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your
problem.
If you intend to send any error or debug messages to
the gphoto
developer mailing list <[EMAIL PROTECTED]>,
please run
gphoto2 as follows:
env LANG=C gphoto2 --debug --list-files
Please make sure there is sufficient quoting around
the arguments.
I can issue the command: gphoto2 --list-folders.
I can not issue the command gphoto2 --list-files. And,
I could not issue anyother gphoto2 command option
after I once got one error output. I have to turn off
and turn on my A70 for list folders.
Thanks,
Reno
