Using cgminer with the Bitmain Antminer U1 USB

Download

Download the latest version of cgminer. At the time of writing, this is version 4.1.0.

$ wget http://ck.kolivas.org/apps/cgminer/cgminer-4.1.0.tar.bz2
$ tar xf cgminer-4.1.0.tar.bz2
$ cd cgminer-4.1.0

Compile

Compile cgminer with support for Icarus. If you don't do this, cgminer won't recognize the Antminer U1 and will fail with a "No known USB devices".

$ ./configure --enable-icarus
$ make -j5

Optional:

Confirm that cgminer recognizes your Antminer U1 by running sudo ./cgminer -n. If it does, you will see something like the following output:

$ sudo ./cgminer -n
 [2014-03-13 23:40:18] USB all: found 12 devices - listing known devices
.USB dev 0: Bus 4 Device 4 ID: 10c4:ea60
  Manufacturer: 'Silicon Labs'
  Product: 'CP2102 USB to UART Bridge Controller'                    
 [2014-03-13 23:40:18] 1 known USB devices       

Run

Run cgminer. I'm running it as root, which is probably a terrible idea, but I didn't feel like setting up the USB hotplug permissions and udev rules.

$ sudo ./cgminer -o stratum+tcp://<pool>:<port> --userpass <user>:<pass>

What hash rate can you achieve with this method? I was thinking of selling my asic on as it is too slow for btc (I don't want to damage it)..
