Symptom: On Kaby Lake Refresh systems (T480, X280, X1 Carbon 6th, X1 Yoga 3rd...), when installing Windows 10 1703 (RS2) and previous versions of Windows 10, certain drivers show up as Other Device or show up with an exclamation point (bang) in Device Manager. The issue includes camera devices previously found under the Imaging class, as wells as Fibocom Wireless devices, in the Network class.
Cause: The current set of drivers validated for these systems are specifically for Windows 10 1709 (RS3). Microsoft has changed at least one Class ID in Windows 10 (1709) RS3, the Imaging class, where camera devices used to be found, to the Camera class. This change impacts implementations of Windows 10 1703 (RS2) since the Camera class does not exist, but the device drivers are written for the new class.
In regards to the Fibocom Wireless card, the root cause lies in the driver being written specifically for Windows 10 1709 (RS3) and it not being reverse compatible with previous versions of Windows 10.
So far, the impacted systems are, but not limited to, L380, L380 Yoga, L480, L580, P52s, T480, T480s, T580, X1 Carbon 6th, X1 Yoga 3rd, X280, and X380 Yoga.
Resolution: Installing Windows 10 1709 (RS3) will resolve the issues. We are currently working with the impacted hardware component vendors to validate appropriate drivers for Windows 10 1703 (RS2) and previous versions.
