Manual Device Splitting
You can use the Split Vid/Pid Device policy to specify the vendor and product IDs of a composite USB
device that you want to split. You can also specify the interfaces of the components of a composite USB
device that you want to exclude from redirection. View does not apply any filter policy settings to
components that you exclude in this way.
IMPORTANT If you use the Split Vid/Pid Device policy, View does not automatically include the
components that you have not explicitly excluded. You must specify a filter policy such as Include Vid/Pid
Device to include those components.
Table 15-5 shows the modifiers that specify how Horizon Client handles a Horizon Agent device splitting
policy setting if there is an equivalent device splitting policy setting for Horizon Client. These modifiers
apply to all device-splitting policy settings.
Table 15‑5. Splitting Modifiers for Device-Splitting Policy Settings on Horizon Agent
Modifier Description
m (merge)
Horizon Client applies the Horizon Agent device splitting policy setting in addition to the
Horizon Client device splitting policy setting.
o (override)
Horizon Client uses the Horizon Agent device splitting policy setting instead of the
Horizon Client device splitting policy setting.
Table 15-6 shows examples of how Horizon Client processes the settings for Exclude Device From Split by
Vendor/Product ID when you specify different splitting modifiers.

Horizon Agent does not apply the device splitting policy settings on its side of the connection.
Horizon Client evaluates the device splitting policy settings in the following order of precedence.
n
Exclude Vid/Pid Device From Split
n
Split Vid/Pid Device
A device splitting policy setting that excludes a device from being split takes precedence over any policy
setting to split the device. If you define any interfaces or devices to be excluded from splitting,
Horizon Client excludes the matching component devices from being available for redirection.
Examples of Setting Policies to Split Composite USB Devices
Set splitting policies for desktops to exclude devices with specific vendor and product IDs from redirection
after automatic splitting and pass these policies to client computers:
n
For Horizon Agent, set the Allow Auto Device Splitting policy to Allow - Override Client Setting.
