HOW TO: Apply USB Audio Video Redirection patch with N-series Firmware v1.3.7

Summary:

An optional patch is available for N-series firmware version 1.3.7 that improves USB audio and video redirection behavior in certain applications within a XenDesktop environment. Deployments that will benefit from this patch include call centers operating within a XenDesktop environment that make use of applications dependent on audio via USB headsets, and environments making use of applications that require the use of a USB webcam. The patch is not recommended for deployments that make extensive use of video playback as the changes made can reduce audio performance in those situations.
