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. Horizon 7 does not apply any lter policy seings to
components that you exclude in this way.
I If you use the Split Vid/Pid Device policy, Horizon 7 does not automatically include the
components that you have not explicitly excluded. You must specify a lter policy such as Include Vid/Pid
Device to include those components.
Table 4-5 shows the modiers that specify how Horizon Client handles a Horizon Agent device spliing
policy seing if there is an equivalent device spliing policy seing for Horizon Client. These modiers
apply to all device-spliing policy seings.
Table 4‑5. Splitting Modifiers for Device-Splitting Policy Settings on Horizon Agent
Modifier Description
m (merge)
Horizon Client applies the Horizon Agent device spliing policy seing in addition to the
Horizon Client device spliing policy seing.
o (override)
Horizon Client uses the Horizon Agent device spliing policy seing instead of the
Horizon Client device spliing policy seing.
Table 4-6 shows examples of how Horizon Client processes the seings for Exclude Device From Split by
Vendor/Product ID when you specify dierent spliing modiers.

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