T3i (600) connects but Xsi (450) and 6D do not

[alexmcconahay]

I can get the 600 to connect. Just fine--takes pics.

The 450 just goes to the "Camera Not Found" and "Connection Problems" Helper screen.

The 6D says it found the camera, and then goes to a "SDK error....." (of some sort...sorry, I did not copy it ) and will not connect.

 

All with both Battery and AC converter.

 

All with the same Cables, etc. And whether I plug/unplug USB cables, turn off/on the camera, and call a new instance  of BYE.

 

Any ideas what to check?

Hi Alex,

What version of BYE?  The full number.

However, all of these 3 cameras have been tried, tested, and true.  The fact that you have 2 supported cameras that gives you low-level errors like this points to a Canon/Windows driver issue. This is just a guess for now.

First things first.

1) Confirm your BYE version

2) Confirm which Canon driver you choose in BYE when connecting your cameras.  Canon or Canon210?  You should choose Canon for all of these 3 models.

3) Does Windows see the cameras?  Specifically those that do not connect.

4)  Does EOS Utility connect to all 3 cameras and if they do can you take pictures with all 3 of them in EOS Utility.

That should help to isolate the issue.

thanks, I will give that a try next time I am out in the desert. 

Could it have something to do with the fact that I was using SGP and BYE at the same time. SGP was really misbehaving (no plate solve, frozen computer, etc) until I gave up on BYE, and closed it. Then SGP worked fine. (Using a CCD camera with SGP).

Unless SGP still had a -hard- connection to the cameras, and that it was no letting go, then this could have been the issue.  Only one software can connect to a physical camera at a time.  This is an SDK limitation.  I suspect this may have been the issue.

PLEASE READ AND REPLY.

When asking a question or reporting an issue state the full 3-part numeric version number of BYE, as displayed in the BYE title bar. This information provides context to help in answering your post. It is very important.

For example, you have 3 cameras that were released by Canon at 3 different times. If you are trying to connect to a camera that was released after your version of BYE was released then that would be the most likely reason for a connection failure with that camera but not the others.
