Unable to open shutter - DSUSB


domsel

Question

Hi All,

I've again got time to do some AP and picked up a new scope and trying to get my old imaging setup working again. I have the following setup:

- VirtualBox Running Windows XP SP3 32bit
- Canon 20D Astromodded  (I know, I know, it's old)
- Shoestring DSUSB
- BYE detects my 20D and is able to initiate imaging session
- However, once started, the shutter opens/closes and I get an error "DSUSB Error: Unable to open shutter" 
- But it does open and close, just not in line with the exposure parameters I've provided. And it does download the image.
- When running DSUSBCheck everything works fine, including opening and closing the shutter.
- screenshot and log added

Anybody have an idea? Operator error, or something faulty?

Thanks,

Matt

You seem to be doing everying right.

1) I see however that you have selected RAW+JPG images.  Some older cameras have issues with both are selected.  Try RAW only and see if this makes a difference.

2) Make sure that in-camera mirror lock is turned off.

3) Make sure that in-camera noise reduction is turned off.

Keep us posted.

Hi Guylain,

Thanks for your quick reply and suggestions:

- In-camera mirror lock was already turned off
- In-camera noise reduction was already turned off

But your first suggestion is interesting. I never select JPG as option, so gathered this was an operator error accidentally on my side. I set it to RAW only and retried. Still the same error.

But on closer inspection, it seems that BYE somehow triggers the RAW+JPG option again. I set the camera to RAW only, BYE detects this properly, but once I start an imaging session, BYE instantly shows RAW+JPG instead of RAW. Of course not sure if that is also causing the DSUSB error, but as mentioned before, using DSUSBCheck shows no issues. 

It's strange, since BYE *does* trigger the shutter to open, but it closes immediately thereafter and throws the error.

Any suggestions would be welcome.

Thanks,

Matt
