hey cool thanks! I guess i can load up bfgminer too, i saw some pages about it. Now all i gotta figure out is if the raspberry has enough Watts to deliver and has a good usb3 - with power.
By powered USB switch you mean a USB block you install on the raspberry?
This is gonna be a fun project!

I currently run 4 moonlanders (3 v1.2, 1 v1.1) on a pi, running minera with the custom bfgminer compiled. The moonlanders are tweaked to v.95(as high as I wanted to go) running off a superbpag 7 port hub.
