1. Download the latest version of cgminer (version 4.6.0) from here:
Link: http://ck.kolivas.org/apps/cgminer/
2. Download Zadig Windows Driver: http://zadig.akeo.ie/
3. Plug in the power of your miner and connect USB cable to the computer.
Windows will recognized the USB miner but will fail to to install a driver. This is OK.
4. Run Zadig. Use the drop-down to find the "CP 2120 USB to UART Bridge Controller" entry. If it doesn't show, select "Options->List All Devices"

5. Set the new driver to be WinUSB and click Install (or Re-Install) driver.

6. If it is successful you will see this message:

7. Extract cgminer to your chosen location
8. Create a textfile with your mining pool information inside, then rename it to “startmining.bat” and put it inside cgminer folder.
You can also download a premade bat file from here: https://www.dropbox.com/s/pvguut5n72qn932/startmining.bat
Extract it to your cgminer folder and edit the information to match your own mining pool.
(i.e. mining pool, username, password) See example below:
cgminer.exe --icarus-options 115200:1:1 --rock-freq 350 -o stratum.btcguild.com:3333 -u eyebootdaddy_1 -p 12345
-o = mining pool address : mining pool port number
-u = workername from your mining pool
-p = password for your worker
--rock-freq = controls speed (possible values =280 - 350)
9. Save your startmining.bat file.
10. Run the startmining.bat file and wait a few seconds for cgminer to detect the New R-Box.
11. If cgminer does not recognize the device (like in the picture below) then you will have to unplug the USB cable and replug it in again until it is recognized.
