For example:
# defaults write com.vmware.viewusb AllowAutoDeviceSplitting true
# defaults write com.vmware.viewusb SplitExcludeVidPid vid-03f0_Pid-2a12
# defaults write com.vmware.viewusb SplitVidPid "'vid-0911_Pid-149a(exintf:03)'"
# defaults write com.vmware.viewusb IncludeVidPid vid-0911_Pid-149a
Composite USB devices consist of a combination of two or more devices, such as a video input
device and a storage device. The first line in this example turns on automatic splitting of composite
devices. The second line excludes the specified composite USB device (Vid-03f0_Pid-2a12) from
splitting.
The third line tells Horizon Client to treat the components of a different composite device
(Vid-0911_Pid-149a) as separate devices but to exclude the following component from being
redirected: the component whose interface number is 03. This component is kept local.
Because this composite device includes a component that is ordinarily excluded by default, such as a
mouse or keyboard, the fourth line is necessary so that the other components of the composite
device Vid-0911_Pid-149a can be redirected to the remote desktop.
The first three properties are splitting properties. The last property is a filtering property. Filtering
properties are processed before splitting properties.
Example: Excluding a USB Ethernet Device
One example of a USB device you might want to exclude from redirection is a USB Ethernet device.
Suppose that your Mac is using a USB Ethernet device to connect the network for the Mac client system
to a remote desktop. If you redirect the USB Ethernet device, your local client system will lose its
connection to the network and the remote desktop.
If you want to permanently hide this device from the USB connection menu, or if you have set your
remote desktop to autoconnect USB devices, you can add an exception to exclude your Ethernet
connection.
defaults write com.vmware.viewusb ExcludeVidPid vid-xxxx_pid-yyyy
In this example, xxxx is the vendor ID and yyyy is the product ID of the USB Ethernet adapter.
USB Redirection Properties
When creating filtering rules, you can use the USB redirection properties.
