Overview of RemoteFX USB Redirection for Workspot Desktops and Apps
Microsoft added significant improvements and capabilities of USB redirection with RemoteFX. There are now numerous categories of devices supported, including scanners, webcams, multi-function printers, and more. Many of the differences and benefits between RemoteFX USB redirection and the previous iteration, RDP High-Level Device redirection, are outlined in the table below:
Requirements To Enable RemoteFX USB Redirection

Additional Information
Some devices will be redirected by using high-level device redirection, while others will be redirected using RemoteFX USB redirection. The table below outlines how devices are redirected.
Server Device Security
More granular control of redirected devices can be achieved by using the Device Installation Restrictions policy settings. Devices can be restricted by device setup classes, device IDs, and whether or not the user is an administrator.
Modify the following group policy setting on the client as desired:
Computer Configuration\Administrative Templates\System\Device Installation\Device Installation Restrictions
Verifying Proper Installation of RemoteFX USB Redirection
In Device Manager, expand Universal Serial Bus controllers, and find any of the USB root hub, USB hub, or USB controller devices. Right-click the device, then click Properties. On the Driver tab, click Driver Details. If RemoteFX USB redirection is properly installed and enabled, tsusbflt.sys will appear in the list of driver files provided.
Verifying Settings in Workspot Client
Ensure the Workspot client is configured to support device redirection to the Session Host server by verifying the devices are enabled under the following setting:
