My proxmark3 easy doesn’t seem to have two usb ports. And no, the proxmark3 easy I’m currently using wasn’t from you guys, it was from Aliexpress (I know, I know, but I’m in college, I don’t have much money). I followed that guide, as well as this one for when I got stuck: Proxmark for Cyborgs - Getting started and cloning your first badge!. I did order another proxmark3 easy from you guys just a bit ago, just in case I bricked mine by accident.
