Version Effect of USB Policy Settings on USB Redirection
5.1 or later 5.1 or later USB policy settings are applicable to both View Agent and View Client. You can use
View Agent USB policy settings to block USB devices from being forwarded to a
desktop. View Agent can send device splitting and filtering policy settings to View
Client. You can use View Client USB policy settings to prevent USB devices from being
redirected from a client computer to a desktop.
5.1 or later 5.0.x or earlier USB policy settings apply only to View Agent. You can use View Agent USB policy
settings to block USB devices from being forwarded to a desktop. You cannot use View
Client USB policy settings to control which devices can be redirected from a client
computer to a desktop. View Client cannot receive device splitting and filtering policy
settings from View Agent. Existing registry settings for USB redirection by View Client
remain valid.
5.0.x or earlier 5.1 or later USB policy settings apply only to View Client. You can use View Client USB policy
settings to prevent USB devices from being redirected from a client computer to a
desktop. You cannot use View Agent USB policy settings to block USB devices from
being forwarded to a desktop. View Agent cannot send device splitting and filtering
policy settings to View Client.
5.0.x or earlier 5.0.x or earlier USB policy settings do not apply. Existing registry settings for USB redirection by View
Client remain valid.
If you upgrade View Client, any existing registry settings for USB redirection, such as HardwareIdFilters,
remain valid until you define USB policies for View Client.
The
Linux client does not support USB policies. You can use the USB policies for View Agent to control which
USB devices are allowed to be forwarded from a Linux client to a desktop.
Configuring Device Splitting Policy Settings for Composite USB Devices
Composite USB devices consist of a combination of two or more different devices, such as a pointing device
and an audio input device, a video input device and a storage device, or a communications device and a storage
device. If you want to allow one or more of the components to be available for redirection, you can split the
composite device into its component interfaces, exclude certain interfaces from redirection, and create a
separate filter for each interface.
Table 8-16 shows how the value of the Allow Auto Device Splitting setting determines whether View Client
attempts to split composite USB devices automatically. By default, automatic splitting is disabled.

By default, View disables automatic splitting, and excludes any audio-output, keyboard, mouse, or smart-card
components of a composite USB device from redirection.
