BFGMiner U3 support

[winterjak]

Hi,
I'm fairly new to mining, I've been using 2 antminer s5 miners which have been working great but my 2 new U3 version 2's don't seem to be working correctly. I'm currently using bfgminer 5.1 for mac. it shows cpu 0 and cpu 1, so at least the two u3's are found but for speeds i'm getting an average speed of .58Mh/s total?!  don't U3's start around 30-60gh/s each?

OCL 0: off
CPU 0: 581.0/493.7/287.3kh/s
CPU 1: 581.0/493.7/287.3kh/s

also messages of
error -54: Enqueueing kernel onto command queue.
OCL 0 Failure, disabling!
attempting to reinitialize OCL 0

-- but it still connects to the pool

more detail?
what version of BFGminer you running?
what commands you using?
and if I recall correctly, just like linux, you have to tell your mac-os that its usable for normal users, basically a chmod to the ttl port..
now, I have a U3, but not a mac (unless i borrow one off one of my customers, but i don't think they'd like me to mess around with things like that on their system...)

Also, have you tried on a windows system, or a linux system?
