Hello,

I'm using two antminer U2 (working well), and I have just added a bitfury twin.

Bfgminer 3.99 or 3.10 doesn't work if both models are connected (I'm compiling 4.00 version). Alone, bitfury works.

With cgminer 3.4.3, all worked, U2 at normal speed, but the bitfury is under 100MH/s.... alone, she is 4GH/s easily.

Is someone have ideas to try ?

The usb hub is powered enought (3A, for just the U2 and bitfury connected).
