So, I'm not comfortable hacking together my own USB powered HUB. Most likely I will buy one or more. If I have an old MacBook Pro early 2011. Everything in USB system report says Current Available (mA) is 500. Can I purchase external AC powered USB 3.0 hubs and attach it to the USB 2.0 port? Would I be able to use Moonlander 2 at full power this way? Or do all ports have to be USB 3.0 capable from start to finish? I hope the question makes sense... It'd be a shame and waste to run less than 5 MH/s on the Moonlander 2 I pre-ordered.
