Can a FULL NODE be configured to be a STANDARD Node so another FULL Node can control it? I guess the real question is can a Desktop Class Control Be "Dumbed Down" to a USB Controlled Hashboard?
Yes you can.
I removed the entire "computer" part from one of my Full nodes (make sure you disconnect the cable from the computer part that connects to the miner part underneath. It's like 6 screws that hold it in place) and then just use the USB cable from your full node to connect to the newly created standard.
