Do you know of any hubs that keep all the ports on a single level? I already purchased and installed a 2nd RaspPi and have 20 miners on each, but in the future it might be helpful for others that want to control more from a single unit (which I bet it can since 20 miners only results in around 10% utilization).
Probably too expensive but here is a 49 port designed for continuous enterprise use:
How about 2 of these?: http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=6436&seq=1&format=2
One for each of the Raspberry Pi's 2 ports? We should be able to conceivably connect up to 48 miners per RPi... Anyone had any experience with these or know its internal topology?
The one from monoprice looks nicer.
