How many USB Devices can be added to one Synology NAS

Hello,
We are using VirtualHere with one Synology NAS. We installed 3 USB Hubs with 10 slots per Hub, so that we should be able to get 30 devices running in summery.
Unfortunately it seems to be a limit either in the Software VirtualHere or in the Synology because we only get 24 devices online. The other 6 devices will not be added to the device List.

Is your hub separately powered?
