Today i tested the Microsoft Cinema HD together with the IGEL Universal Desktop LX/OS.
The camera worked with a small issue in a Citrix Session with HDX Realtime and local without any issue with a installed Skype Client thru custom partition.
To get Microsoft WebCam to work with HDX Realtime and Linux i need to make a small modification to my Citrix webinterface site, see also here: https://blog.cloud-client.info/2012/07/13/using-xenapp-65-or-xendesktop-56-together-with-microsoft-lync-and-igel-linux-based-thin-clients/
