I read mentioned thread and just tried it - nothing happens, unrecognized device. There aren’t any “interesting features”, nor “any features”.
Still can’t understand, why should i connect router to PC through USB, especially when can’t be powered from it.
I was just curious about it, quoting user Normis from that thread
This is a microUSB port so that you can use your standart phone charger cable to plug the router into your PC and configure it directly over USB (something like a replacement for serial port). There are also some other exciting features planned for this port.
