Weird noises with Allo USBridge Signature

Hm I was to believe that the USBridge was just a device to power your PI and to isolate its USB port the right way. Now it seems Allo uses special software?
I’m not so happy to hear this, especially since it seems that Allo is not eager to corporate with Volumio.
I will make my complaint at Allo.
For now I have to see how this SSH stuff works…
