After starting up the USB Redirector TS Edition - Server you can see its main window:
The window displays a list of active RDP sessions. When connection is established, you can see a list of shared USB devices that are available for connecting from workstation. Normal users can see their own session only. Administrators can see all the sessions by selecting Program > Show USB Devices From Other Sessions menu item.
Each USB device has a name and an icon next to it that shows the device status. Depending on the status, you can carry out different operations with this device. For detailed information please see USB Device Status section. You can use the corresponding Program Menu items or buttons on the Toolbar to connect, disconnect or perform other operations with devices.
