Deploying for Rich and Thin Clients


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 "Settings > RDP > Devices > Use plug and play devices."

If this checkbox is not shown on the Client, it means you need to go to Workspot Control and enable "Allow Redirection of Plug and Play Devices" under the Security Policy defined for your users' Group.
