Examples of Setting Policies to Split Composite USB Devices
Set splitting policies for desktops to exclude devices with a specific vendor and product IDs from redirection
after automatic splitting and pass these policies to client computers.
Table 8-19. Use View Agent Policies to Specify Device Splitting Policy Settings
USB Splitting Policies on View Agent USB Splitting Policies on View Client
Exclude VidPid From Split set to
o:vid-xxxx_pid-yyyy.
Allow Auto Device Splitting set to Allow - Override
Client Setting.
Any settings for Allow Auto Device Splitting and
Exclude VidPid From Split on View Client are
overridden by View Agent.
Allow Auto Device splitting for desktops and specify policies for splitting specified devices on client
computers.
Table 8-20. Use View Agent and View Client Policies to Specify Device Splitting Policy Settings

Client Setting.
The setting for Allow Auto Device Splitting on View
Client is overridden by View Agent.
Split Vid/Pid Device set to
vid-0781_pid-554c(exintf:00;exintf:01) to split a
specified composite USB device and exclude interface 00 and
interface 01 from redirection.
NOTE You must also specify a filter policy such as Include
Vid/Pid Device set to vid-0781_pid-554c, which allows
View Client to redirect the other components of the device.
Configuring Filter Policy Settings for USB Devices
Filter policy settings that you configure for View Agent and View Client establish which USB devices can be
redirected from a client computer to a desktop.
You
can configure USB device filter policy settings in the policy settings for View Agent and View Client. When
you connect to a desktop, View Client downloads the View Agent USB policy settings and uses them in
conjunction with the View Client USB policy settings to decide which USB devices it will allow you to redirect
from the client computer.
View applies any device splitting policy settings before it applies the filter policy settings. If you have split a
composite USB device, View examines each of the device's interfaces to decide which should be excluded or
included according to the filter policy settings. If you have not split a composite USB device, View applies the
filter policy settings to the entire device.
Table 8-21 shows the modifiers that specify how View Client handles a View Agent filter policy setting for an
agent-enforceable setting if an equivalent filter policy setting exists for View Client.
Table 8-21. Filter Modifiers for Agent-Enforceable Settings
Modifier Description
m (merge) View Client applies the View Agent filter policy setting in addition to the View Client filter
policy setting.
o (override) View Client uses the View Agent filter policy setting instead of the View Client filter policy
setting.
Table 8-22 shows examples of how View Client processes the settings for Exclude Vid/Pid Device when you
specify different filter modifiers.
