I was able to fix it! iTunes can now see my iPhone5.
I followed these instructions:
And re-installed the "Apple Mobile Device USB Driver".
- Right-click the Apple iPhone, Apple iPad, or Apple iPod entry in Device Manager and choose Update Driver from the shortcut menu.
- Click "Browse my computer for driver software."
- Click "Let me pick from a list of device drivers on my computer."
- Click the Have Disk button. (If the Have Disk option is not present, choose a device category such as Mobile Phone or Storage Device if listed, and click next. The Have Disk button should then appear.)
- In the "Install from Disk" dialog, click the Browse button.
- Use this window to navigate to the following folder:
C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers.
- Double-click the "usbaapl" file. (This file will be called "usbaapl64" if you have a 64-bit version of Windows. If you don't see "usbaapl64" here, or if there is no Drivers folder, look in C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers. instead).
- Click OK in the "Install from Disk" dialog.
- Click Next and finish the driver-installation steps. Open iTunes to verify that the device is recognized properly.
