As already mentioned in this thread, this isn't strictly true.
There is USB "on the go" (aka OTG [1]); this has even a protocol
to switch masters. That makes sense for mobile devices, which
have to play slave when being attached to a computer (sync and
things) and have to play master when stuffing a storage stick
into them.

But at any time there can only be one master on an USB tree.

And the hardware has to play along.

USB is no replacement for networking, no.
