Windows Server 2008 R2. Doesn't license the RDP device?

Question

Windows

Good afternoon!
Is available Server 2008 R2. Works as a terminal server. Purchased 25 "per device" RDP licenses.
23 clients - Windows 7SP1, 1 client - Windows CE 6.0
24 of them are issued and work normally, today I'm trying to connect another client on Windows CE 6.0.
It connects fine and logs into the server's remote desktop. Next, on the server, I open the "Remote Desktop Licensing Manager" snap-in and I do not see a new PC in the list with issued licenses (neither a temporary nor a permanent license has been issued). There are no errors in the system logs ....
Maybe someone came across?
