I note:

b) WpdMtp.dll
They are not equivalent, as their names and version numbers
indicate.Which of these is supposed to be loaded for your camera? What
do the registry keys point to? Is there a key conflict? Are both drivers
loaded? Etc. There's some kind of conflict here, IMO.
I vote with the people who suggest uninstalling/reinstalling. Since
"reinstall" in W7 means letting W7 find the correct driver, this should
work. I'd delete all camera related keys first. W7 will create whatever
keys are needed when you reinstall. I'd also move the *.dlls to a safe
place to force W7 to find the correct one "on the web" during reinstall.
Alternatively, one could try them out one at a time.
Good luck.
By uninstall/reinstall do you mean the problem device via Device
Manager? I have done that (repeatedly), but not with the drivers first
removed. I'll try that.
I'd move them to a safe location with a name change, just in case.
"Delete all camera related keys" I'm not quite sure what you mean
here. While I used to be an application programmer, a senior field
engineer, and a FCC licensed technician, that was a while back and I
am not very familiar with the innards of Windows.
The keys are in the registry, which among other things refers to
locations of drivers, etc. Win uses it to find what's needed for devices
etc to work properly. Running regedit to clean up the registry ranges
from dead easy to very scary, depending on what's installed. But you may
want to explore the registry anyhow. Use Find to locate relevant keys.
It's a "learning opportunity", as they say. ;-)
Thanks for the reply.

You're welcome, it's last-resort, based on your comment that the USB
ports are OK, and that the same problem occurs on different ports.
Another last resort comment: the issue could be in the camera's
firmware, and/or the flash card's OS. Try reading the card with a card
reader.
Good luck.
OK, here is what I did. I removed (actually renamed to .bak) all the
files that were listed as drivers in my original post EXCEPT the usb
driver, since I would be in trouble if my keyboard and track ball stop
working.
Then I brought up device manager, and selected the bad device and went
to "properties/driver."
It said "Reinstall device drivers for this device, To reinstall the
drivers, click Reinstall Drivers"
So I did that, selecting automatic search. After a prolonged period,
with lots of internet activity, the message was "best driver is
already installed."
Dang. That's the same message as before!
Is it getting weirder?
Just as a suggestion -
Why don't you try and reload your Motherboard drivers off the CD. or you
could see if there is any newer USB driver software on the MB site.
I appreciate your help Rob.
ASUS does not provide ANY CD with the computer. (Cheap bastards. The
computer does not even have a case cooling fan). I have reinstalled
the AMD driver software I downloaded from ASUS. This includes the
audio, video, USB, USB3, RM-Bus drivers. No change in the problem
It would seem that its a USB port problem.
One other question, would be, are you using the front USB ports or rear?
The ASUS has six USB2 and two USB3 ports. Two of the USB ports have
the keyboard and track ball. One has the Cannon printer. One has the
AnFi USB sound device. I usually plug the camera into one of the two
front ports, but have also tried rear ports and a USB3 port. There has
been no change in the symptoms.

Not sure what you can do except use a card reader. BTW card readers
don't damage SD or CF cards. Ithink you can buy USB3
I now have 7x32Gb sd cards for my camera and change them all the time
without any detrimental effect.
Since the bulit-in card reader gives the same symptoms as does the
camera, I would be surprised if an external one would work.
Since last post I have disconnected the card-reader and front USB
ports completely. No change in symptoms.
I have also checked the "UpperFIlters" registry entry suggested, again
with no positive results.
All I can say for sure is that the camera and card reader are NOT the
problem. The problem is in Microsoft's WPD drivers or associated
settings.
I have found many references to this exact same problem on the web,
dating back as far as 2008 and Vista. A very common comment is "This
has been going on for years. Why hasn't Microsoft fixed this?" Yeah.
The problem always involves WPD, but the actual hardware that reveals
it varies (cameras of various brands, ipods, etc.)
On these pages a variety of cures have been suggested. For each some
say it worked and others say it didn't. So far none have worked for
me. Apparently there are many things that can trigger the problem.
Thanks for your suggestions. I really appreciate your help.
By the way, I posted the problem on the Microsoft "hardware and
drivers" forum. It only drew one response, and my response to that one
went unanswered. Too bad MS doesn't actually have a real support
system.
