Generic USB redirection can be used together with optimized support. If you enable generic USB redirection, configure Citrix USB devices policy settings for both generic USB redirection and optimized support. The Citrix policy setting Client USB device optimization rules is a specific setting for generic USB redirection, for a particular USB.

Citrix support for peripherals attached to a client device is a fundamental functionality leveraged by the Citrix Server Based Computing (SBC) model. Support for many client-side peripherals exists. Therefore, when either using local or remotely published applications, end-users can seamlessly utilize their peripheral device resources.
Client-side peripherals are supported in one of two basic methods:- Device Level Redirection – This method involves redirection (also called “mapping”) of the high-level device as recognized by the operating system, such as keyboards, mice, or printers. Such devices are not detected by the operating system by the hardware ports to which they connect, but rather by the device itself. For example, whether a keyboard has a USB or Serial port connector, or a printer has a Parallel, Serial, or USB connector, they are detected by the operating system as keyboards and printers. In the latter scenario that is for a parallel printer, the printer mapping functionality is used; LPT port redirection, which is described in the following section, does not play a role.
Port Level Redirection – This method involves redirection of the low-level port itself. This includes COM, LPT, and USB ports. These ports are generically identified as ports by the operating system and traffic to them is redirected between server and client. XenApp versions earlier than 7.6 supports the generic redirection of only COM and LPT ports on the client device. Generic redirection of USB port is supported XenApp 7.6 and later. Refer to Generic USB Redirection in XenApp 7.6.

USB Port Level Redirection
Citrix does not support USB devices that require low-level port redirection. Because of the large number of USB-based devices that are available and the proprietary nature of each manufacturer implementation of USB, it has not been possible to date to make a generic USB port redirection solution available as a standard part of the product. Citrix is, however, investigating the possibilities for creating USB solutions for particular devices at the high-level device redirection as previously described. Contact Citrix Systems for the possibility of creating customized solutions for such products, or for information on future support for them within the standard product.USB Drivers and ICA Clients
Note that all of the USB peripheral support above assumes the existence of a proper USB device driver for the operating system on the client device, and for a corresponding Citrix ICA Client for that same operating system that supports the mapping functionality at hand. For example, not all Citrix ICA clients support the use of smart cards whether or not a device driver from the manufacturer exists.USB Printers on Macintosh Computers
The Citrix ICA Client for Macintosh OS provides general support for printers attached by using Macintosh USB ports. Some manufacturers supply printer drivers that allow a print file to be sent directly to specific USB printers. Another alternative is to print by using a network print server, instead of using the Client Printer Mapping functionality in the ICA Client. Refer to Citrix Documentation - Mac Printing to Map client devices.USB Printers on Windows Based Terminals
USB support for Windows Based Terminal client devices is vendor dependent. Contact the Windows Based Terminal vendor for the latest information about USB solutions for their devices.Additional Resources

Objective
Citrix Usb Monitor Driver
This article describes how to determine USB drivers are configured correctly on the Online Plug-in.
Background
After installing the Online plug-in, the USB drivers must be loaded in the operating system so that a local USB device appears when connecting to a Virtual Desktop session.
Instructions
Using the WinObj tool from sysinternals, you must see an entry under DeviceCtxUsbMonitor. If the ctxusbm is not present, the device driver has not loaded.
Run the following command at the command prompt to verify that the Citrix USB driver files are located in the correct directory in the file system:
dir %Windir%ctxusbm.sys /s/b
Run the following command to determine if the USB driver service shows any errors:
c: >sc query ctxusbm
If the USB driver is not loaded and running, you will need to determine what is causing the service from not installing or stopping it from starting.
The setupapi logs will determine if any errors occur during the installation of the driver. The logs are located in the directory under %windir%inf:
Verify any errors in the event viewer.
If no errors appear, you must uninstall then reinstall the online plug-in with setupapi logging set to the maximum verbosity:
