So I have 4 USB erruptors, up until three days ago, I ran them off an old laptop, windows 8, cgminer, 1.2ghz, no bother. Couple of days ago, I got a Pi, installed raspbian, compiled cgminer with all product extensions. Cgminer runs, it can see all 4 cards and get them hashing.. at an average of 350mh/s total. That's less than 100 mh/s per card and they were working fine as of last week.

I'm using the same usb3 hub (with a 4A PSU) as i did on the previous computer, however, on the pi, i am plugged into a usb2 socket, but that shouldn't affect bandwith quite so bad.

Does anyone know what happned/how to fix it?

ROI is hard to get running at full power, at less than a quarter, i'm just heating the house (in july)

thanks

EDIT this might be the wrong sub, if so I'm sorry and could you point me to the right place?

It's not an oddity at all. You can't use a USB3 hub on a Pi. 

If you'd spent 3 seconds Googling the issue, you'd have discovered that...

Look for USB 2.0 hubs.  I'm currently running four Erupters plus the Pi off a single D-Link DUB-H7, and it's been stable for the 12 hours I've had it going.
