USB-Redirection - Which Version of Windows do I need

Hi,

i´m trying to get USB-Redirection to work in my virtual Desktop Enviroment. But it doesnt work till now..

Having read several articles and blog entries, I noticedthatthe needed windows versionfor virtual Desktops isnot mentioned anywhere.

Here is one of the Remote Desktop Services Blog:

RemoteFX USB Redirection in Windows Server 2012 and Windows 8

So, do I need Windows Enterprise for the virtual Desktops?

Thanks

Stefan
