Newbie questions - capturing images from Canon PowerShow A520

[Jyri Hovila-3]

Hello, world!

I finally bought my first digital camera in the hope that I could use  
it as a high quality web camera. Naturally, I soon found myself from  
a swamp of new and exotic problems. ;)

I'm using OpenBSD 3.7 and gphoto2 version 2.1.6. Gphoto does not  
recognize the camera correctly (it's identified as 'Canon:PowerShot  
SD400 (normal mode)'), but all the "offline" functions still work ok:  
I can download files from the camera etc.

My question is: is it possible to capture images directly from the  
camera using this version of gphoto2? I mean can I actually take  
pictures using gphoto2 without touching the camera? If it is not  
possible yet, could this kind of functionality be implemented in any  
near-future version of gphoto?

Thanks in advance!

- Jyri

Remote capture is not supported for the SD400.

Hmm. Could you send me the output of "cat /proc/bus/usb/devices"?
It seems we got the product ID wrong for your camera.

Well, not if the camera doesn't have that capability. Some newer
Canon consumer cameras don't; check your Canon software manual.

OpenBSD does not have the /proc virtual filesystem. What kind of  
information do you need exactly?

The camera does have this capability - it is possible to take  
pictures using Canon's Windows / Mac software, which is one of the  
most horrible specimen of software engineerin skill I've seen for a  
while. =P

Yours,

Jyri

lsusb -v

It will give you the USB IDs.

Hi!

> lsusb -v

This command isn't available in OpenBSD either. I tried to compile  
the (Linux) usbutils package, but it didn't work out.

Dmesg shows the following information:

     ugen0: Canon Inc. Canon Digital Camera, rev 1.10/0.01, addr 2

Yours,

Jyri

It is on FreeBSD as far as I remember. Check your documentation. It
should tell you how to get the information

Which does provide NOTHING.

Well, I'm looking for the product ID for your camera. It might be even
more helpful to send me the complete --debug output from, say, gphoto2
--list-all-files -R.
