  1. Download Zadig Windows Driver: http://zadig.akeo.ie/


  1. Insert one BFx2 miner into a USB port on your Windows machine.

          If you have never installed any FTDI drivers, then Windows will fail to install a driver. This is OK.


  1. Run Zadig. Use the drop-down to find the "Single RS232-HS" entry.  If it doesn't show, select "Options->List All Devices"


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


  1. Extract cgminer to your chosen location


  1. Right mouse click, select edit on the #Mine.bat file inside cgminer to change to your own information

             (i.e. mining pool, username, password) See example below:


          cgminer.exe -o stratum.d7.lt:3333 -u iloveppcoin.2 -p 12345 --bxm-bits=54


-o = mining pool address : mining pool port number

-u = workername from your mining pool

-p = password for your worker

--bxm-bits = controls speed (possible values = 50, 51, 52, 53, 54, 55, 56)


  1. The fastest --bxm-bits value is usually 54, but you can experiment with your miners. Some might be different.


  1. Save your #mine.bat file.


  1. Open #mine.bat and start mining!
