This actually makes sense as the power distribution on motherboards and
laptops is not as even as one likes it to be. Add to it the
availability of space to add capacitors to compensate for momentary
inequalities in power consumption. And add the pickiness of audio
circuits about power supply and you might end up with a usb audio
device connected to your laptop that restarts the stream every time you
move the mouse (worst case;-)). And it runs rock-stable when connected
to the other side of the laptop…
