I'm not sure if theres a better place to put this than here, just wanted to add some info. If anyone can think of a better thread for me to move this.

I was playing around with my old board again, and one of the USB Boot pads has about 3.3v which looks like a USB data pin high level.

I took a usb cord I had with loose wores, and trid probing that, with unhelpful results.

I grounded my USB cord to the logic board, and probed those two pins, and with one of the data lines connected to the 3.3v one, my computer would register SOMETHING has connected to USB, but it didn't get any Device ID or anything else useful, the USBDeview app just change the USB port to purple, and highlighted it as some knd of connection.
