Configuring USB Redirection on a Mac OS X Client
Administrators can configure the client system to specify which USB devices can be redirected to a remote
desktop.
You can configure USB policies for both View Agent, on the remote desktop, and Horizon Client, on the
local system, to achieve the following goals:
n
Restrict the types of USB devices that Horizon Client makes available for redirection.
n
Make View Agent prevent certain USB devices from being forwarded from a client computer.
n
Specify whether Horizon Client should split composite USB devices into separate components for
redirection.
Composite USB devices consist of a combination of two or more devices, such as a video input device
and a storage device.
Configuration settings on the client might be merged with or overridden by corresponding policies set for
View Agent on the remote desktop. For information about how USB settings on the client work in
conjunction with View Agent USB policies, see the topics about using policies to control USB redirection, in
the View Administration document.
Syntax for Configuring USB Redirection
You can configure filtering and splitting rules to exclude or include USB devices from being redirected to a
remote desktop. On a Mac OS X client, you configure USB functionality by using Terminal
(/Applications/Utilities/Terminal.app) and running a command as root.
n
To list the rules:
# sudo defaults read domain
For example:
# sudo defaults read com.vmware.viewusb
n
To remove a rule:
# sudo defaults delete domain property
For example:
# sudo defaults delete com.vmware.viewusb ExcludeVidPid
n
To set or replace a filter rule:
# sudo defaults write domain property value
For example:
# sudo defaults write com.vmware.viewusb ExcludeVidPid vid-1234_pid-5678
IMPORTANT Some configuration parameters require the VID (vendor ID) and PID (product ID) for a
USB device. To find the VID and PID, you can search on the Internet for the product name combined
with vid and pid. Alternatively, you can look in the USB Log file after you plug in the USB device to the
local system when Horizon Client is running. For more information, see “Turn on Logging for USB
Redirection,” on page 47.
n
To set or replace a splitting rule for a composite device:
# sudo defaults write domain property value
