UPDATE 8/4/14 I updated the guide to apply to S3's. Thanks for the kind emails about my previous tutorials! The S3 tutorial is here:

http://www.rubicite.com/Tutorials/AntMinerS1Tutorial.aspx UPDATE 1/21/14 I strongly recommend that you use BFGminer for Antminer U1's. The tutorial below is for CGMiner. I have made the switch. It is simpler for a single device, and it just works with multiple devices.
I am keeping my tutorial up to date on my website here:
http://www.rubicite.com/Tutorials/AntminerU1Tutorial.aspxThe following is from early January:
How to Install, Use, and Overclock an AntMiner U1 Bitcoin ASIC Miner in Windows1. Visit the
https://github.com/AntMiner/AntGen1/tree/master/cgminer This is your resource for documentation and software.
2. Download the special branch of CGMiner for AntMiner U1's from GitHub
https://github.com/AntMiner/AntGen1/blob/master/cgminer/cgminer-run-windows-20131224.zip (click the "raw" button to download the zip).
3. Unzip that file into a folder on your drive. Remember the location. For this example, I will assume G:/CGMiner
4. Download the CP210x USB driver
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx - download the one for your operating system.

6. Plug in your AntMiner U1 to a USB port on your computer. If you had already done this, unplug it and plug it back in.
7. Download Zadig for your operating system from
http://zadig.akeo.ie/8. Run the Zadig Executable.
9. Go to the options menu, and select "List All Devices"

12. When that is done, close Zadig.
13. Create a new text file and save it as AntMiner.CMD on your desktop.
14. The contents of this command file should be as follows:
g:\cgminer\cgminer.exe --bmsc-options 115200:20 -o MY_POOL_URL:PORT -u MY_WORKER_NAME -p MY_WORKER_PASSWORD --bmsc-freq 078115. Double Click the command file. If you get any errors:
- Confirm that your pool settings are correct
- Confirm that the path to your cgminer executable is correct in the command file
- If it is still not working, unplug the AntMiner U1, plug it back in, and try again
- Finally, if it is still not working, reboot your computer and consider trying a different USB port.
16. To overclock your AntMiner U1, you will change that last part of the AntMiner.CMD file. The number following "--bmsc-freq" will change.
- For 1.8 GH/s, use 0881
- For 2.0 GH/s, use 0981
- For 2.2 GH/s, use 0A81
Keep in mind that the AntMiner gets VERY hot VERY quickly when you overclock. Your must add additional cooling to your device. I recommend a strong fan blowing cool air directly onto your AntMiner U1.
