Hardware/devices missing

Hi ( frankb :) ),

I recently installed ocs server and a couple of agents/clients so i can check  if everithing is working fine. Although i can see some basic information (CPU, RAM, IPs...) i'm unable to see hardaware/devices of those pc's in my server (keyboards, printers...). I dont know if i'm missing something here.
I think it's a server problem because i can check all information needed using the option "Show Inventory information" of the clients.

so sorry for my bad english,

Many thanks.

AI: server version: 2.2.1 running on Ubuntu 18.04.

Agent/Client version 2.0.5 running on Windows 10 (both of them).
