Horizon 7 applies the device splitting policy settings before it applies any filter policy settings. If you have
enabled automatic splitting and do not explicitly exclude a composite USB device from being split by
specifying its vendor and product IDs, Horizon 7 examines each interface of the composite USB device to
decide which interfaces should be excluded or included according to the filter policy settings. If you have
disabled automatic device splitting and do not explicitly specify the vendor and product IDs of a composite
USB device that you want to split, Horizon 7 applies the filter policy settings to the entire device.
If you enable automatic splitting, you can use the Exclude Vid/Pid Device From Split policy to
specify the composite USB devices that you want to exclude from splitting.
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 filter policy settings
to components that you exclude in this way.
Important 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 filter policy such as Include
Vid/Pid Device to include those components.
Table 45 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 45. 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 46 shows examples of how Horizon Client processes the settings for Exclude Device From
Split by Vendor/Product ID when you specify different splitting modifiers.
