Using USB devices with remote desktops and published applications has the following limitations:
n
When you access a USB device from a menu in Horizon Client and use the device in a remote
desktop, you cannot access the device on the local computer.
n
USB devices that do not appear in the menu, but are available in a remote desktop, include human
interface devices such as keyboards and pointing devices. The remote desktop and the local
computer use these devices at the same time. Interaction with these devices can sometimes be slow
because of network latency.
n
Large USB disk drives can take several minutes to appear in the desktop.
n
Some USB devices require specific drivers. If a required driver is not already installed on a remote
desktop, you might be prompted to install it when you connect the USB device to the remote desktop.
n
If you plan to attach USB devices that use MTP drivers, such as Android-based Samsung smart
phones and tablets, configure Horizon Client so that it automatically connects USB devices to your
remote desktop. Otherwise, if you try to manually redirect the USB device by using a menu item, the
device is not redirected unless you unplug the device and then plug it in again.
n
Do not connect to scanners by using the Connect USB Device menu. To use a scanner device, use
the scanner redirection feature. This feature is available for Horizon Client when used with View
Agent 6.0.2 or later or Horizon Agent 7.0 or later. See Using Scanners.
n
Webcams are not supported for USB redirection using the Connect USB Device menu. To use a
webcam or audio input device, you must use the Real-Time Audio-Video feature. See Using the Real-
Time Audio-Video Feature for Webcams and Microphones.
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. Audio input and output devices work
well with the Real-Time Audio-Video feature. You do not need to use USB redirection for those
devices.
n
You cannot format a redirected USB drive in a published desktop on an RDS host unless you connect
as an administrator user.
n
The published application auto-connect at startup and auto-connect when inserted features do not
work with global application entitlements.
You can connect USB devices to a remote desktop or published application either manually or
automatically.
Note Do not redirect USB devices such as USB Ethernet devices and touch screen devices to a remote
desktop or published application. If you redirect a USB Ethernet device, your client system loses network
connectivity. If you redirect a touch screen device, the remote desktop or published application receives
touch input but not keyboard input. If you have set the remote desktop or published application to
autoconnect USB devices, you can configure a policy to exclude specific devices.
