Can't access admin server GUI

Hi,

I'm running USB server on windows, and can connect to devices from clients...

But when I go to http://server_ip:7575, I can't get admin GUI, 

and I see this error logs in the server -

ERROR : Error received message is too big   

#2

There is no admin webpage.

#3

So is there a way for me to manage users and groups ?

For ex - I have 2 devices connected to server, and two users that want to use this devices, how can I manage them.

groups- i have a device that contains two USB ports, can i make them has a group ?

 

thanks for the help !
