Hooked up 100 USB miners, using 2 raspberry PI.

In my testing each raspberry can only handle about 45 miners, after that the additional miners just don't get detected.  However after you get into the 35+ range you start to get a much higher rate of HW errors.

So I had to split the miners 34 per raspberry and 32 on my desktop, got another raspberry in the mail, so will run 3 total to handle all 100 miners.

Currently cooled with just a standard room fan, but the rig really doesn't run that hot so I think I'll replace that fan with a small USB fan for each hub.
