Wyse has their TCX software, which is licensed separately from the Thin Client itself. One version of the TCX software is for USB Redirection and the other for Multi-media. As a previous post stated, the TCX software was implemented by VMware, however this only is the case when using the View Client on a re-purposed physical client desktop

The TCX software, running from the Wyse Thin Client, will provide an enhanced multi-media experience when connecting to a Virtual Desktop over RDP
