Do not use USB device redirection when the network latency is higher than milliseconds. USB devices rely on drivers to function properly and some devices require special drivers.

For example, timing-sensitive devices might not operate correctly over high-latency low-bandwidth links. Use optimized support instead where possible. Some USB devices require high bandwidth to be usable, for example a 3D mouse used with 3D apps that also typically require high bandwidth.

If bandwidth cannot be increased, you might be able to mitigate the issue by tuning bandwidth usage of other components using the bandwidth policy settings. For more information, see Bandwidth policy settings for Client USB device redirection, and Multi-stream connection policy settings.

Some USB devices are security-sensitive by nature, for example, smart card readers, fingerprint readers, and signature pads. USB devices are often used to distribute malware. This situation applies whether generic USB redirection or optimized support is used. Only enable support for the USB devices that you need. Configure both generic USB redirection and optimized support to meet this need.

For Citrix Workspace app versions, see the Citrix Workspace app feature matrix. If you are using earlier versions of Citrix Workspace app, see the Citrix Workspace app documentation to confirm that generic USB redirection is supported. Some types of USB devices are not supported for generic USB redirection because it would not be useful to redirect them:.

To enable generic USB Redirection, and not require manual redirection by the user, configure both Citrix policy settings and Citrix Workspace app connections preferences. Specify that devices are connected automatically without manual redirection. For thin clients, consult the manufacturer for details of USB support and any required configuration. USB devices are also automatically redirected when the connection bar is not present. Users can explicitly redirect devices that are not automatically redirected by selecting the devices from the USB device list.

For more information, the Citrix Workspace app for Windows user help article, Display your devices in the Desktop Viewer. Only configure generic USB redirection for use with a webcam if the webcam is found to be incompatible with HDX multimedia redirection. For example:. You can get this information from the device vendor. Device rules are not intended to prevent this behavior. Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system.

Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Do not edit these product default rules. Instead, use them as a guide for creating administrator override rules, which is explained later in this article. The GPO overrides are evaluated before the product default rules. If you are using the ADM template file, you must create rules on a single line, as a semicolon-separated list.

The following example shows an administrator-defined USB policy rule for vendor and product identifiers:. The following example shows an administrator-defined USB policy rule for a defined class, subclass, and protocol:. Optimized support is provided for USB mass storage devices. This support is part of Citrix Virtual Apps and Desktops client drive mapping.

Drives on the user device are automatically mapped to drive letters on the virtual desktop when users log on. The drives are displayed as shared folders that have mapped drive letters. To configure client drive mapping, use the Client removable drives setting. Control them using Citrix policies. The main differences are:. If both generic USB redirection and the client drive mapping policies are enabled and a mass storage device is inserted either before or after a session starts, it is redirected using client drive mapping.

When both generic USB redirection and the client drive mapping policies are enabled and a device is configured for automatic redirection and a mass storage device is inserted either before or after a session starts, it is redirected using generic USB redirection.

USB redirection is supported over lower bandwidth connections, for example 50 Kbps. You can control whether users can copy files from their virtual environments to their user devices. To prevent users from adding or changing files and folders on mapped client-devices, enable the Read-only client drive access policy setting. When adding this setting to a policy, ensure that the Client drive redirection setting is set to Allowed and is also added to the policy.
