Third-party video drivers and Citrix HDX RealTime Optimization Pack
The Microsoft Windows operating system installed on some thin client terminals often does not include Windows USB video class (UVC) drivers for web cameras, although these drivers have been included with standard Microsoft Windows XP and Vista operating systems since SP2. When you install a web camera on a terminal device, the installation program may report that it does not have required files.
We recommend that you use the standard Windows device drivers for webcams because vendor-supplied drivers can sometimes cause crashes and Blue Screen events on certain platforms (especially 64-bit Windows).
