Configuring the Custom RDP Settings for USB Redirection
Applies To: Windows Server 2008 R2 with SP1
To enable USB Redirection, configure the custom RDP settings to redirect devices. Administrators can use custom RDP settings to configure RD Web Access so that USB Redirection is automatically configured for all users.
You can also configure the RDP settings on a client computer by using Remote Desktop Connection. To do this, in the Local Resources tab, under the Local devices and resources heading, choose the devices to be redirected.
To configure the custom RDP settings
Log on to the RD Connection Broker server, as an Administrator.
Click Start, point to Administrative Tools, point to Remote Desktop Services, and then click Remote Desktop Connection Manager.
Expand RD Virtualization Host Servers.
Right-click Personal Virtual Desktops, and then click Properties.
Click the Custom RDP Settings tab.
In the Custom RDP settings box, type usbdevicestoredirect:s:\, and then click **OK*.
The usbdevicestoredirect:s:* RDP file setting automatically redirects all devices that do not have drivers installed on the client computer or if the device does not have another method for redirection. If you want to control which devices are redirected, you can add the interface class GUID for each device. This forces the device to be redirected by using USB redirection in RemoteFX even if another type of redirection is available. To add more than one device, each interface class GUID must be separated by using a semicolon.
