5.2

View 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, View 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, View 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.
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 8-17 shows the modifiers that specify how View Client handles a View Agent device splitting policy
setting if there is an equivalent device splitting policy setting for View Client. These modifiers apply to all
device-splitting policy settings.
Table 8-17. Splitting Modifiers for Device-Splitting Policy Settings on View Agent
Modifier Description
m (merge) View Client applies the View Agent device splitting policy setting in addition to the View
Client device splitting policy setting.
o (override) View Client uses the View Agent device splitting policy setting instead of the View Client
device splitting policy setting.
Table 8-18 shows examples of how View Client processes the settings for Exclude Device From Split by
Vendor/Product ID when you specify different splitting modifiers.

View Agent does not apply the device splitting policy settings on its side of the connection.
View 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, View Client excludes
the matching component devices from being available for redirection.
