Set the Exclude All Devices policy to true, on the agent side or on the client side, as appropriate.
If you set the Exclude All Devices policy to true, Horizon Client prevents all USB devices from being
redirected. You can use other policy settings to allow specific devices or families of devices to be redirected.
If you set the policy to false, Horizon Client allows all USB devices to be redirected except those that are
blocked by other policy settings. You can set the policy on both View Agent and Horizon Client. The
following table shows how the Exclude All Devices policy that you can set for View Agent and
Horizon Client combine to produce an effective policy for the client computer. By default, all USB devices
are allowed to be redirected unless otherwise blocked.

Include all USB devices
false (include all USB devices) true (exclude all USB devices)
Exclude all USB devices
true (exclude all USB devices)
Any or not defined Exclude all USB devices
If you have set Disable Remote Configuration Download policy to true, the value of Exclude All Devices
on View Agent is not passed to Horizon Client, but View Agent and Horizon Client enforce the local value
of Exclude All Devices.
These policies are included in the View Agent Configuration ADM template file (vdm_agent.adm). For more
information, see “USB Settings in the View Agent Configuration ADM Template,” on page 165.
Using Log Files for Troubleshooting and to Determine USB Device IDs
Useful log files for USB are located on both the client system and the remote desktop operating system. Use
the log files in both locations for troubleshooting. To find product IDs for specific devices, use the client-side
logs.
If you are trying to configure USB device splitting or filtering, or if you are trying to determine why a
particular device does not appear in a Horizon Client menu, look in the client-side logs. Client logs are
produced for the USB arbitrator and the Horizon View USB Service. Logging on Windows and Linux clients
is enabled by default. On Mac OS X clients, logging is disabled by default. To enable logging on Mac OS X
clients, see Using VMware Horizon Client for Mac OS X.
When you configure policies for splitting and filtering out USB devices, some values you set require the VID
(vendor ID) and PID (product ID) for the 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 client-side log
file after you plug in the USB device to the local system when Horizon Client is running. The following table
shows the default location of the log files.
Table 14‑2. Log File Locations
Client or Agent Path to Log Files
Windows client
%PROGRAMDATA%\VMware\VDM\logs\debug-*.txt
C:\Windows\Temp\vmware-SYSTEM\vmware-usbarb-*.log
Windows agent (on
remote desktop)
%PROGRAMDATA%\VMware\VDM\logs\debug-*.txt
Mac OS X client
/var/root/Library/Logs/VMware/vmware-view-usbd-xxxx.log
/Library/Logs/VMware/vmware-usbarbitrator-xxxx.log
Linux client
(Default location) /tmp/vmware-root/vmware-view-usbd-*.log
If a problem with the device occurs after the device is redirected to the remote desktop, examine both the
client- and agent-side logs.
