i have multiple miners of different origins and working automatically
Turns out that bfgminer accepts multiple -S driver:all commands, even though it doesn't work that well.
cgminer recognizes the devices upon insertion, so everything is all right.
Now I have something like
BF1 0: | 2.317G/2.275Gh/s | A: 4166 R: 54 HW:267 WU: 32.5/m
BF1 1: | 1.589G/1.589Gh/s | A: 2975 R: 0 HW:446 WU: 22.7/m
BAJ 0: max 44C 1.00V | 6.836G/6.881Gh/s | A:10891 R:318 HW:184 WU: 97.7/m
BXF 0: 41.6C | 4.606G/4.634Gh/s | A: 7139 R: 38 HW: 5 WU: 65.4/m
BXF 1: 48.1C | 4.070G/5.143Gh/s | A: 9515 R: 31 HW: 3 WU: 71.9/m
BXF 2: 40.3C | 4.734G/4.692Gh/s | A: 8195 R: 0 HW: 10 WU: 66.5/m
BXF 3: 46.1C | 4.809G/4.889Gh/s | A: 8322 R: 93 HW: 2 WU: 68.5/m
BXF 4: 41.7C | 5.385G/5.449Gh/s | A: 9090 R: 24 HW: 5 WU: 76.3/m
working fine on my mac, but not on my minepeon.
