Device Specific Registry Keys

Introduction

This document explains the use of all the registry keys used by the "Universal Driver Package".

In order for device specific changes to be effective, the device must be restarted (i.e. disable the device and then enable it) in Device Manager, or the system must be rebooted.

For user specific changes to become effective, it is necessary to log off and log back on again.
