Device Manager Portable Devices: This device cannot start (Code 10)

I was trying to figure out why only one of my idevices was showing my on my computer. I checked device manager and under portable devices I see Apple iPhone. Then when I plug in my iPad it shows up under USB devices as Apple Mobile Device USB Composite Device and it has a yellow exclamation point. WHen I try to update the driver thats when I get the Code 10 message. I disconnect both devices and plug in the iPad 1st. I look under portable devices and I see Apple iPad. Then I plug in the iPhone and it's listed USB devices with the exact same listing the iPad had. No matter what I do I cannot get both to appear under portable devices at the same time. Whatever device gets plugged in 1st appropriately shows up under portable devices. When I plug in the a 2nd device thats where the problems start. Has anyone ever heard of such a bizarre problem? I've swapped USB slots and cables and keep on getting the same thing. I am at a complete loss on this.

Interesting. I have never hooked up my iPad and iPhone to my system at the same time. I never needed to. So I did just to see if I had the same results as you and they came up fine for me in iTunes, iFunbox and Explorer. Do you have anything odd in the device manager? An exclamation mark?
