I was curious if anyone knew what the4 pins internally on the MK VII are?
I assumed it was USB and so tried a 4 pin header to USB-A cable with the thought of maybe shucking my Alfa, modding the case for a couple more antenna and having some 802.11AC, leaving the external port available for something else.
A POC test on a couple adapters with the cable on the 4 pin and nothing is being detected. The MK VII reboots if you remove/replace an adapter while hot, so I'm starting to think I'm flat wrong, or maybe I've got a short in the cable. Also flipping the header on the pins and I get no boot at all.
Of course I'll keep tinkering, because that's what we do, but it would be nice to know if I was chasing my tail.
