Solved Canon Digital Cameras - USB Drivers Do Not Work Through Reboots

[sygnus21]

With that, we know it's not a Windows 7 /Canon camera compatibility issue per se.

However, it "could" be something to do with Enterprise and the way it manages stuff. But that seems a far off shot in the dark. To me, Windows 7 is Windows 7 is Windows 7, driver wise but...

And to answer an earlier question.... and this point in time, I'm completely lost as to a solution.

I agree with Windows is Windows is Windows but this issues is so bizarre I am beginning to wonder. :shock:

Yeah it is a baffling one.

Have you Googled the issue to see if there's anything out there like what you're experiencing?

Earlier on in this thread I googled extensively and indeed that is where much of my possible solutions came from. In particular the idea of setting the camera via it's menu to a PTP setting instead of PC. This if I recall was on a user support Forum, I then contacted Canon Support and they told me that there was no Menu item to change this detail so that confused the issue somewhat. There's one outfit saying do this and Canon saying there was no facility to do it!
I have been thinking of this problem this morning and recall that the OP said that the Registry Key for the Canon cameras looked very different from the keys for the other makes. Just perhaps if the OP were to post a screenshot showing clearly the various keys we might be able to get Brink to put his "Magic Registry key" hat on and look at this for us. It does look like a slight anomoly with Windows Enterprise version as I think I understand correctly that the Canon cameras work OK with other Versions of Win 7. I wonder if it is possible that the Enterprise edition has a different Firewall and that is blocking the cameras? Does anyone think this might be possible?

Here are some screenshots:

If I boot into a WinPE CD/DVD/USB environment, open the registry on the local machine and delete the entire registry key the computer will work with the Canon Camera until you reboot. Once the key has been created and you reboot the camera will no longer work.

Update New Information: I have discovered why the camera does not work after reboots; Windows will NOT load the Windows Camera Driver. It is not in memory. If I plug in a Nikon camera which works correctly it will load the Windows Camera Driver and now the Canon will work just fine because the driver is already loaded. When I reboot the Canon will not work again because the driver is not loading. If I repeat the steps and plug in the same Nikon or another Camera then the Canon will work again. -WS

Well Brink has looked at it and he can't immediately see where the problem is.
One more thing to try. Can you boot up in Safe Mode and see what happens? Your A/V will not run in SM so perhaps the Firewall will be off too! Cutching at straws now but perhaps worth a try!

 

[sygnus21]

Have you looked into maybe a Windows update, or lack thereof, causing the issue?

Issue - *Solved* I Need help - Win 7 - losing drivers after shut down/reboot
Solution - *Solved* I Need help - Win 7 - losing drivers after shut down/reboot. Unfortunately the "fix" is vague, but the OP does indicate it was an update issue.

Then there's this post here, also indicating an update causing the problem - http://www.sevenforums.com/drivers/36134-must-reinstall-nic-usb-drivers-after-every-reboot.html

Safe Mode: No difference
A/V Off: No difference
Firewall Off: No difference

The Windows Driver Foundation - User Mode Driver Framework service needs to be changed from MANUAL to AUTOMATIC. This fixes the Canon Camera issues.

For you command line junkies (like me) use this in an elevated Command Prompt:

sc config wudfsvc start= auto

This took me a very long time to figure out. -WS

Thank you to everyone for their suggestions. This forum is amazing! -WS

Thanks for the update. BTW it this something particular to 7 Enterprise? Strange you had to do this to get the Canon's drivers to stay put :shock:

Thanks.

Great question: I am still trying to figure out why this setting is set to MANUAL on our machines and AUTOMATIC on the home machines (well only one checked so far) I have everyone checking their working machines a home.

I am thinking it was some security update?? Searching the internet, I have read that this service leaks a bit and will start using a lot of memory, plus it is vulnerable to some types of virus threats. How true that is I don't know just what I read. -WS

My Windows Drivers Foundation is set to manual. I have never changed it. What is the default?

Hmmm.... sounds like what was reported in the links I posted earlier. Both state they think it was an update that caused their problems.

Sorry; I will go away.

I don't know the answer to your question as I've never look at that section, thus why I didn't answer you.

Delighted you have found the answer. This one was beginning to get under my skin. I wouldn't dare ask what route you took to get there but very well done. What a satisfying feeling you must have now! Lots of Rep to you

We have never changed this setting either. I think some MS security update or something that was installed changed it from AUTOMATIC to MANUAL, seems like AUTOMATIC is the default. But don't quote me, because I have no proof either way. Still researching....

 

[WindowsStar]

Sorry; I will go away.

Edit: The service is: Windows Driver Foundation - User Mode Driver Framework

No need to go away, the more people we have looking at this the better. I would like to have the answers to the following questions:

#1 What is the default service start up for the service?
#2 What changed it from AUTOMATIC to *MANUAL?
#3 Why do some cameras start the service but the Canon's DO NOT?
#4 Are there security risks for the service?
#5 Can A/V software or viruses exploit the service?

* MANUAL = Start on demand for this service. We have also noted that it seems (no proof yet) that the install of IE10 and 2 or 3 reboots changes the setting from AUTOMATIC to MANUAL. We are trying to find a few machines that do not have IE10 on them to test this (fortunately or unfortunately all our machines have IE10 on them). -WS

Wel my Home Premium version is set to "Manual" I have definitely never touched it so I assume "Manual" to be the default. But then it besgs the question, How come some of your users have Auto set in their home computers. Very Confusing. I wouldn't have thought that an update would alter these settings but thenstranger things happen at sea!

A bunch of luck and days of work to figure this out. I probably should flow chart it and post it here but I am not sure I have the time or energy, this one problem set me back weeks worth of work. UGH!

Do you have a Canon Camera? If so would you plug it in to a USB port, read the SD card/Picture Memory. Then unplug it and put it back. It should work. Now unplug and reboot, then plug it back in to the very same USB port and is should not work. Then start the Windows Driver Foundation - User Mode Driver Framework service and magically the camera will work, no reboot or unplug/plug needed. I would like to see if you have the same issues/symptoms. Many thanks.
