Introduction USB Manager is a useful tool for managing USB devices and redirection on devices running HP ThinPro. As virtual desktop infrastructure (VDI) becomes more powerful, more and more companies are replacing their desktop computers with thin clients and expecting same-as-desktop behavior, including the use of USB devices. USB devices such as flash drives, webcams, and speakers enrich the user experience; thus, many customers want this function.

Device mapping/virtual devices Device mapping, or virtual devices, uses the concept of virtual devices to maximize the performance of specific types of USB devices. The USB device communicates locally to the thin client and then relevant data is transferred over a virtual channel that is designed specifically for the data payload. By transmitting only the important data and reducing the granularity of handshaking, this method can reduce latency and improve performance for real-time devices.

USB Manager overview USB Manager can be used to configure both which devices are redirected and, depending on the protocol, how the devices are redirected. USB Manager can also disable all device redirection. Generally, the default options do not need to be changed and most USB devices are redirected automatically to the remote session in the most efficient way possible. For troubleshooting or for specific use cases, you might need to use this tool to adjust the settings.

Devices tab This tab can be used to control the method of redirection for a specific USB device that is plugged into the system. This setting overrides the standard settings for a USB device of that class. This selection persists after restarting the thin client. To force the USB device to use USBR for Citrix or VMware connections, select the checkbox to the left of the device name. For RDP connections, USB Manager controls only whether a USB device is redirected.

Common use cases Disabling mass storage devices USB flash drives and other mass storage devices present a security risk for certain customers. To prevent these USB devices from being redirected: 1. In the Classes tab, clear the Mass Storage checkbox. 2. To disable mass storage devices from being accessible locally on the system running HP ThinPro, in the Protocol tab, clear allow devices to be mounted.
