Specifically which anker 10 port usb 3.0 hub are you using? Could you please provide a website link to the item you have if available? Thank you.
the hub i'm using in that picture is the much discussed 12 port usb hub from saitechi. it wouldn't power more then 3 erupters. i've got an anker 10 port usb 3.0 now (and two more en route) running five of them plus the fan and my cell phone charger no problem.
