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.
