sorry had a bad night thanks for the response, same architecture as a pi really was hoping some pi users were about
here's a raspi user, currently driving 3 moonlander2 and an old rpi2 for bfgminer off a 'rather pricey' and very powerful USB hub at 796, above they become unstable in a rather unpredictable way. i suspect the usb WLAN dongle i have to use in my setup as a part of the problem - i think i read about USB bus saturation being a possible problem SOMEWHERE, but didn't debug in this direction any further yet...
anyways, the basic setup worked like a breeze. plug your MLDs in, run bfgminer as described in a lot of places, watch your MLDs have fun. however 9 more moonlanders are on their way to me, and i am eager to see if i can drive all i then have reliably with a bunch of hubs and one rpi3, which will eliminate the need of a seperate dongle.
considering that could actually fail, i have a bunch of rpi2 around, and a bananapi routerboard (BPI-R1). i'm kinda sure i'll find a way to make it work reliably, somehow.
sweet, i might be slightly better off as the odroid is usb 3, I'm looking at this hub:
The USB 3.0 ports on this hub are special because all of them can load any connected mobile devices with up to 2.4 A. The intelligent chipset determines the best charging rate for all models.
found some cheaper hubs from a company called orico claim 36 watt on a 10 port, 12v 3a psu
