Xiaoguang Wu 6a9a46ac47 DM USB: xHCI: workaround for Stop Endpoint Command handling
This patch is one workaround to resolve a crash issue for certain brand
touch screen (eGalaxTouch EXC7200-7368v1.01). The formal fix should
follow the xHCI spec to stop xfer and generate transfer completed event
trb prior to Stop Endpoint Command complete event trb. It should be a
big change and for short term, do nothing for the stop endpoint command
which is no other side effect be observed so far.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
