I've gotten my hands on some AntMiner U2s but bfgminer is not seeing them.
This is on a Raspi.
./bfgminer-3.10.0/bfgminer -S antminer:all -o stratum.myfuckingpool.com:3333 -u demonmaestro_usb -p 1
I got my Antminer U2 today also, no luck so far. I'm using Windows 7 Pro 32-bit. SiLab drivers installed. Windows sees the device in corect port. The miner has a steady Red LED but BFGMiner has No New Device Found. I can't find any info from Bitmain for these either. Well, except for pricing.
