1. The First Glance
Welcome to BI Official User Guide.
Manufactured by BI , the Scrypt USB Miner is being produced in two colors:
Green and Blue. BI Scrypt USB Miner is one of the fastest and easiest to deploy
entry-level miners. With its own integrated cooling solution, it includes a 25mm fan,
so no need to come up with clumsy external fan solutions to keep these cool. It can
mine any Scrypt algorithm coins such as: Emerald Crypto Coin (EMD), Verge (XVG),
DigiByte (DGB), Bitcoin (via Nicehash), Litecoin (L C), Einsteinium (EMC2), Florin
(FLO), Gulden (NLG), GameCredits (GAME), Dogecoin (DOGE), Viacoin (VIA),
Myriad (XMY) along many other smaller Scrypt-mineable coins.

2. ccessories & Connection
2a. Where to purchase powered USB hub
You will need a powered USB hub that is capable of supplying at least 1-2A per port
(5-10W @ 5V). Some computers provide enough power for BI miner to work, but
this is not guaranteed.
If your computer is not up to the task or you want to use two, three, five or maybe
even 10 BI miners, I recommend to purchase this USB hub:
Sipolar 10 Port USB Professional Mining Hub
2b. Connection
a) Connect your USB hub to your host computer. Make sure the power adapter is
plugged in as well.
b) Insert the BI USB Stick Miner into the USB hub via the USB port.
2c. Correct connection order
Make sure that you plug in powered USB hub into your computer first. Only once you
do that, after few seconds, start plugging in your BI miners.

3. Setup (Windows)
3a. Silabs CP210x USB to U RT Bridge VCP Driver
If you purchased the miner from eBay link provided with this Guide, you will receive
software pack containing all required drivers. Download it and unpack the archive to
separate folder.
First, install Silabs CP210x USB to UAR Bridge VCP Driver. I included Windows 10
driver files (Windows 10 only!) in the folder “Silabs Windows 10 Driver” which is in
“Windows” folder. Open the folder and run CP210xVCPInstaller_x64.exe:
After successful install, you will see this screen:

If you have earlier Windows version (Windows 8 etc.), you can go to Silabs website
and download driver directly:

drivers
Unpack downloaded file and run .exe file in similar fashion described above.
3b. Running bfgminer
Navigate to “Windows” folder included with this manual, you will find files similar to

Run any of the .bat files, for example EMD_p2pool.bat. If everything is successful,
you will see a window similar to this one:
It’s important to see device listed here (MLD 0) and hashrate (in MH s).
Once everything is confirmed working, you can exit cgminer by pressing [Q] for Quit.
Now, modify pool settings by editing .bat file – right click on the file and select Edit.
You can enter your own pool settings and addresses and restart cgminer. I’ve also
included few more .bat files for different coins and pools, please have a look. Enjoy!
