Symptoms


When you connect a USB personal healthcare device (such as a glucose meter) to a USB 3.0 port on a computer that is running Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2, the Personal Healthcare Device Class (PHDC) descriptor validation for the USB device fails. In this situation, the USB device cannot be recognized.

Cause


This occurs because of a specification conflict between the PHDC and the USB-defined SuperSpeed Endpoint Companion descriptor.

Status


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
