FIX: An RNDIS USB-enabled device is not recognized when it is connected to a Windows Embedded CE 6.0 R3 device

Symptoms

Consider the following scenario:

  • You run a Windows Embedded CE 6.0 R3-based image that has the SYSGEN_ETH_USB_HOST variable enabled on a CE device.

  • The CE device supports Remote Network Driver Interface Specification¬†(RNDIS)-compatible Ethernet adapters.

  • You connect an RNDIS USB-enabled device such as a Windows phone to the CE device.

In this scenario, the CE device does not recognize the RNDIS device.

Cause

This problem occurs because the USBDeviceAttach function in the RNDIS driver (Usb8023.dll) does not check for the ActiveSync class on the USB descriptor. The RNDIS driver loads and then unloads immediately during the connection.
