Wudfhost.exe crashes when you plug in a USB-ICCD-compliant smart card device into a Windows computer

Symptoms
Assume that you plug in a USB-ICCD-compliant smart card device into a computer that is running Windows 8, Windows Server 2012, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1. In this situation, the Wudfhost.exe process crashes and the smart card interface is not available.
Cause
For Windows 8 and Windows Server 2012, this issue occurs because the USB bulk pipe of the device is not checked by the computer.

For Windows 7 and Windows Server 2008 R2, this issue occurs because the asynchronous reader does not behave as required and causes stack overflow. The stack overflow is caused by an asynchronous read starting from the same thread as the previous one in the completion routine of the previous asynchronous read.
