Show USB WAN connection / Even when not connected

I sometimes use a USB hotspot or a phone tethered via USB to my B One. Is there a reason I can’t see or change any settings on this USB WAN connection unless I physically connect a USB device? I’d like to do some changes even before I connect the USB. When USB is disconnected it disappears off the list entirely and you are unable to make changes unless connected.

Hi…

It is a Linux explanation, about how USB works and why it cannot be modified, when it is not pluged.

The Linux-USB Host Side API — The Linux Kernel documentation.
