P.S.: Having finally got the remote shooting working on my Android-which was broken due to a bug in the 1.1.1 firmware that only arose when it was updated from 1.0.2 or below-I am inclined to think that it is another audacious bug that Canon will have to remedy themselves. That last point made me suspect the cable, but I've tested it & it works fine with a number of other devices. It is not detected as an imaging device, storage device, or even as anything attached to the USB bus.

No pop-ups, no driver install prompt, bubkiss. Thanks for your reply though! The computer is acting as if nothing is plugged in at all.

In the meantime I am totally open to sugestions including any kind of magic, hokum, or witchdoctoring that may fix the problem. I don't have another computer here with me to test the 'it's Microsoft's fault' theory, but I will when I am able (probably later today). I have tested the USB cable on other devices & it works fine. ( probably the most likely culprit) the firmware has another bug.( less unlikely) The EOS Utility is going wonky with the 7D MkII.( somewhat unlikely) Something is amiss with the camera itself.In my humble opinion (which is usually pretty accurate in such matters) there are three distinct possibilities: I know Canon will want to point the finger at Microsoft & I know Microsoft (should I post on their support forums) would also want to point the finger at Canon. I was unable to pair it before it disappeared though. Once or twice-when attempting to connect via WiFi-the camera popped up in the 'EOS Pairing Software' window for a split second. Incidentally, what should it be detected as? An imaging device? That & a storage device?
