*About this software*
|
|
=====================
|
|
|
|
This is libptp2!
|
|
|
|
This library is under developement yet.
|
|
It's designed to use with gphoto2, but can be easily used with any other
|
|
software.
|
|
|
|
There is a sample test_ptp.c code which shows how to use libptp2 without
|
|
gphoto2. You can use test_ptp.c as a quick startup for your own ptp
|
|
application. Vide library.c to see how to use libptp2.
|
|
Sorry, no docs yet :(
|
|
|
|
To compile test_ptp.c type:
|
|
cc -g -O2 -g -Wall -I/usr/local/include/libexif -I../../libgphoto2 -I/usr/local/include -g -Wall test_ptp.c -lusb ptp.o -o test_ptp
|
|
|
|
or something similar :)

==============================================
|
|
|
|
Note that for some HP and Sony cameras you have to switch them to PTP mode
|
|
as in most cases the camera is dual mode: PTP and USB Mass Storage.
|
|
For some cameras it even changes the Product ID number, so don't panic if
|
|
it does not match the one listed above, just switch the mode.
|
|
|
|
Moreover if you heard that your camera is a PTP camera, you may test it
|
|
against this driver even if it's not on the list above. If it's really in
|
|
PTP mode, the USB interface class should be set to 6 (it's called "still").
|
|
You may check it reading /proc/bus/usb/devices, for example:
|
|
|
|
cat /proc/bus/usb/devices | grep "Cls=06"
|
|
|
|
If you seen an output for example like this:
|
|
|
|
I: If#= 0 Alt= 0 #EPs= 3 Cls=06(still) Sub=01 Prot=01 Driver=(none)
|
|
|
|
that means that your camera is a PTP one.
|
|
The ptp driver should detect that camera by interface class as "USB PTP
|
|
Class Camera" and allow downloading the pictures and do other stuff.
|
|
|
|
|

|
|
*Solving and reporting problems*
|
|
================================
|
|
|
|
To solve the problem stick to gphoto2 CLI, forget about the GUI now.
|
|
Use gphoto2 -L to see if it detects camera.
|
|
|
|
If you see something like this:
|
|
|
|
~> gphoto2 -L
|
|
Unable to get descriptor (-1)
|
|
(... lot of other errors ...)
|
|
|
|
it may mean that you're working as user while the usb access is restricted.
|
|
See gphoto2-manual, section "Setting up your system for use with libgphoto2
|
|
and gphoto2", subsection "Setting up permissions for USB ports".
|
|
|
|
If the gphoto2 detects the camera but then fails with some error messages
|
|
please report the bug sending the mail to gphoto-devel@gphoto.org or
|
|
directly to me at: emsi@emsi.it.pl.
|
|
The mail should contain the full output of gphoto2 -L --debug with locale
|
|
language set to _ENGLISH_.
|
|
For example in bash do:
|
|
env LANG=C gphoto2 --debug -L
|
|
tcsh/csh:
|
|
setenv LANG C; gphoto2 --debug -L
|
|
|
|
WARGING!!! Before sending any mail make sure you read the notes in
|
|
"Supported Cameras" above.
|
|
|
|
Enjoy!

Documentation
|
|
|
|
While ptp transactions usage seems to be quite obvious the ptp events
|
|
handling code should be documented.
