I was able to get this working with my usb erupters fairly easily, win7x64. I only have 1 of the BF and 25 of the usb erupters they are currently playing well with each other. Using bfgminer 3.2 the BF was found with the -S BF1:all to start then after it loads I just do M then + to add more devices doing erupter:all and it adds my 25 along side the BF. Was running on 3.2.0 for about 5 hours today with 2.3GH/s from the BF. With 3.5.1 it does report some HW errors (just after 5 min of running), 3.2.0 did not during its run.
