What USB ID does the camer have so we can add it to our list?

"--abilities" uses only the static abilities in the source code,
and the generic PTP camera reports all abilities.

What "--summary" reports is what the cameras actually reports over the wire.


Can you report the standard info:

http://gphoto.org/proj/libgphoto2/support.php 

Record the output of lsusb to get the USB ids.
Record the output of gphoto2 --auto-detect to see if it is detected in a generic way, or by another name. If it is detected already, run the steps below:
Record the output of LANG=C gphoto2 --summary >summary.txt to get generic summary information into the summary.txt file.
Record the output of LANG=C gphoto2 --list-all-config >config.txt to get the configuration tree into the config.txt file.
Record the output of gphoto2 --capture-image to see if capture works already.

This kind of capture was kind of hacky to implement and I also saw stability issues,
but was not able to find out the reason :/

I have to dig out my old Olympus E camera at some point to see if I can improve
stability.
