iPhone not charging in Windows. Driver without iTunes? On a Windows 8 machine, I've connected an iPhone 4s. Windows makes a audible chime for 'device connected', but doesn't allow charging in any USB port.

iTunes isn't installed, and cannot be installed at this time under corporate policy.

The iPhone shows as a generic device / toaster under Control Panel's Devices as below. The iPhone does NOT show as charging.

Is there a driver to install to ensure the iPhone is detected and can charge via USB without installing iTunes?

I've tried:


forcing Windows Update
Just download iTunes, open the .exe file with winrar or some other similar software and then run the AppleMobileDeviceSupport(64).msi executable from there.
