Configuring Remote Desktop Features

Table Of Contents
n
Webcams are not supported for redirection.
n
The redirection of USB audio devices depends on the state of the network and is not reliable. Some
devices require a high data throughput even when they are idle.
n
USB redirection is not supported for boot devices. If you run Horizon Client on a Windows system that
boots from a USB device, and you redirect this device to the remote desktop, the local operating
system might become unresponsive or unusable. See http://kb.vmware.com/kb/1021409.
n
By default, Horizon Client for Windows does not allow you to select keyboard, mouse, smart card and
audio-out devices for redirection. See http://kb.vmware.com/kb/1011600.
n
RDP does not support the redirection of USB HIDs for the console session, or of smart card readers.
See http://kb.vmware.com/kb/1011600.
n
Windows Mobile Device Center can prevent the redirection of USB devices for RDP sessions. See
http://kb.vmware.com/kb/1019205.
n
For some USB HIDs, you must configure the virtual machine to update the position of the mouse
pointer. See http://kb.vmware.com/kb/1022076.
n
Some audio devices might require changes to policy settings or to registry settings. See
http://kb.vmware.com/kb/1023868.
n
Network latency can cause slow device interaction or cause applications to appear frozen because
they are designed to interact with local devices. Very large USB disk drives might take several
minutes to appear in Windows Explorer.
n
USB flash cards formatted with the FAT32 file system are slow to load. See
http://kb.vmware.com/kb/1022836.
n
A process or service on the local system opened the device before you connected to the remote
desktop or application.
n
A redirected USB device stops working if you reconnect a desktop or application session even if the
desktop or application shows that the device is available.
n
USB redirection is disabled in Horizon Administrator.
n
Missing or disabled USB redirection drivers on the guest.
Solution
n
If available, use PCoIP instead of RDP as the protocol.
n
If a redirected device remains unavailable or stops working after a temporary disconnection, remove
the device, plug it in again, and retry the redirection.
n
In Horizon Administrator, go to Policies > Global Policies, and verify that USB access is set to
Allow under View Policies.
