Hi,

     I installed gphoto2 from the repository under Ubuntu-Mate 20.04 and 
tried controlling an old Olympus C-40Z connected to a power supply. I 
got the following:

1) gphoto2 --list-config
/Camera Configuration/Picture Settings/resolution
/Camera Configuration/Picture Settings/shutter
/Camera Configuration/Picture Settings/aperture
/Camera Configuration/Picture Settings/color
/Camera Configuration/Picture Settings/flash
/Camera Configuration/Picture Settings/whitebalance
/Camera Configuration/Picture Settings/focus-mode
/Camera Configuration/Picture Settings/focus-pos
/Camera Configuration/Picture Settings/exp
/Camera Configuration/Picture Settings/exp-meter
/Camera Configuration/Picture Settings/zoom
/Camera Configuration/Picture Settings/dzoom
/Camera Configuration/Picture Settings/iso
/Camera Configuration/Camera Settings/date-time
/Camera Configuration/Camera Settings/lcd-mode
/Camera Configuration/Camera Settings/lcd-brightness
/Camera Configuration/Camera Settings/lcd-auto-shutoff
/Camera Configuration/Camera Settings/camera-power-save
/Camera Configuration/Camera Settings/host-power-save
/Camera Configuration/Camera Settings/timefmt

2) gphoto2 --summary

3) gphoto2 --capture-preview ------- WORKS

4) gphoto2 --capture-movie---------  WORKS

5) However, when evoking gphoto2 --capture-image-and-download or just 
gphoto2 --capture-image

I get:


*** Error ***

ERROR: Could not capture image.
ERROR: Could not capture.

What is wrong? So far I used Sabsik's Cam2Com running under Windows XP 
to control three identical cameras but wanted to finally migrate to 
Linux. There is a problem with the memory card as the camera says that 
it is full and it refuses to format it. With Cam2Com I, therefore, used 
direct download without storing the image on the memory card. Is there a 
way of doing so under gphoto2 as well? Maybe the error is related to the 
defective internal storage. I must say that I have used a number of the 
same type of camera over the years as all finally ended with one or 
another defect that made them useless. But this one still worked!

Thank you very much for hints,

best, Dieter
