newbie want to share with you

i've try it too with bfg miner + rasbian (basicly like debian ins raspberry pi). and yes, it's same like you. i only got 32 active device for hashing from my 38 redfury that connected.

i've try it with cgminer, and "booyyaahh" it connected with all device!!! buuuuutttttt.. it's takes a looong time for running a cgminer, and not stable (maybe because i'm using raspberri pi)

maybe the other or Luke can give us a tips for this?
