Hallo, der Apple Support hat die Lösung nach ein paar Anläufen gefunden. Ich übernehme hier die Antwort:
*After installed iTunes 11.0.2.26, the Apple Mobile Device USB Driver entry is listed, but has an exclamation mark over it. Reinstall the Apple Mobile Device Driver is needed!
Right-click the Apple Mobile Device entry in Device Manager and choose Uninstall from the shortcut menu.
In the resulting dialog box, click OK.
In the Device Manager window, right-click Universal Serial Bus controllers and choose Scan for hardware changes from the shortcut menu.
Windows automatically reinstalls the necessary drivers and attempts to remount the device.*

klarer war für mich folgende Arbeitsanweisung:
**My computer -> right click -> Properties -> Hardware -> Device Manager
-> Universal Serial Bus controllers -> Apple Mobile Device USB Driver**
