USB devices menu option is not present in remote-viewer

I read that there should be option in menu in remote-viewer which shows list of attached to desktop usb devices. But when I connect to virtual desktop and right-click on remote viewer frame - there's no such option (although, there are usb devices connected to my physical PC)r. I use Windows 7 as both client vdesktop, and  have usb redirection service installed on my physical PC. What might be wrong? Remote viewer version is 0.5.3 

 Thank you in advance for any help.
