It can be lucky for others too lacking the information that raspberry likes the DLINK hub.

They are working fine at raspberry pi, had up to four running.



Compile cgminer with the appropiate options or standard bfgminer also.




have a cheap Trust USB Hub and an DLINK 7 port Hub here, both USB 2.0 as 3.0 won't be working.
They both are able to feed two Bi furys 5GH and one Red Fury 2.5 GH with power.
So I have 22.5 GH/s at my raspberry.

They seem to work 10% faster on pi as on windows with USB 3.0 Hubs!

Feel free to also ask for advice
