I was running 5 of the U2s using the FPGA/ASIC miner. I just bought a U3 as an upgrade. I looked at some of the other posts on using CGMiner with the U3, but CGMiner never seemed to see it.
What I tried...
- Removed SiLabs drivers for the U2s
- Fired up CGMiner with this string (from BitMain) in the window:
- --bmsc-options 115200:0.54 –o 184.108.40.206:3333 -u antminer -p 123 --bmsc-voltage 0830 --bmsc-freq 0982 --startdiff 6
It never started hashing. I went hunting for something to tell me what the different switched actually meant, but couldn't find anything. The IP address should probably go, though I really have no idea. I'll continue fiddling, and posting here, but any suggestions are welcome. :-)
Ideally, I'd like to use them all together, but it looks like that is unlikely. :-/
