Configuring Remote Desktop Features

The file structure can be very large, depending on the format. Large USB disk drives can take several
minutes to appear in the desktop. Formatting a USB device as NTFS rather than FAT helps to
decrease the initial connection time. An unreliable network link causes retries, and performance is
further reduced.
Similarly, USB CD/DVD readers, as well as scanners and touch devices such as signature tablets, do
not work well over a latent network such as a WAN.

The redirection of USB scanners depends on the state of the network, and scans might take longer
than normal to complete.
You can redirect the following types of devices to a published desktop or application on an RDS host:

USB thumb flash drives

USB hard disks
Beginning with Horizon 7 version 7.0.2, you can redirect signature pads, dictation foot pedals, and some
Wacom tablets to a published desktop or application. These devices are disabled by default in Horizon 7
version 7.0.2. To enable these devices, delete the Windows registry key settings ExcludeAllDevices
and IncludeFamily from the following path: HKLM\Software\Policies\VMware, Inc\VMware
VDM\Agent\USB. These devices are enabled by default in Horizon 7 version 7.0.3 and later.
You cannot redirect other types of USB devices, and other types of USB storage devices such as security
storage drives and USB CD-ROM, to a published desktop or application.
Overview of Setting Up USB Redirection
To set up your deployment so that end users can connect removable devices, such as USB flash drives,
cameras, and headsets, you must install certain components on both the remote desktop or RDS host
and the client device, and you must verify that the global setting for USB devices is enabled in View
Administrator.
This checklist includes both required and optional tasks for setting up USB redirection in your enterprise.
The USB redirection feature is available only on some types of clients, such as Windows, Mac, and
partner-supplied Linux clients. To find out whether this feature is supported on a particular type of client,
see the feature support matrix included in the "Using VMware Horizon Client" document for the specific
type of client device. Go to https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Important When you deploy the USB redirection feature, you can take steps to protect your
organization from the security vulnerabilities that can affect USB devices. For example, you can use
group policy settings to disable USB redirection for some remote desktops and users, or to restrict which
types of USB devices can be redirected. See Deploying USB Devices in a Secure Horizon 7
Environment.
1 When you run the Horizon Agent installation wizard on the remote desktop source or RDS host, be
sure to include the USB Redirection component.
This component is deselected by default. You must select the component to install it.
