This feature allows end-users to connect their removable devices, such as USB flash drives, cameras, and headsets to the virtual desktop session.

When the HTTPS Secure Tunnel is configured, see Figure 4 and Figure 5, USB traffic is tunneled using HTTPS (TCP) port 443. Where tenants do not require external (internet) access and direct (WAN) connections are used, no Access Point will be required and USB traffic between the Horizon Client and Horizon Agent (desktop) will use TCP 32111.
