The Server does never detect any device

hi,
doesnt matter what i connect. The Server Software wont detect it. I've connected various USB Sticks and WLAN Sticks.
I have a Galaxy S5.

Do I have to do some adjustments on my Phone?

At the top right menu, there is a System Messages option, can you paste those messages here, perhaps that might show the reason.
