Here is a quick direction on how to get you up and running and mining and making Bitcoin with the USB Eruptor Asic miner. By the way, the price of this USB Eruptor had gone down on ebay, at the time of writing this quick blog, the average price is $250, so don’t pay too high for it, it’s not worth at all since ASIC BFL has been shipping 5GH/s machine, it will make difficulty level rise as Bitcoin BTC value dropped.
1: Download and install CGMiner.
A windows binary can be found here: http://ck.kolivas.org/apps/cgminer/.
2: Download and install this driver.
The driver can be found here:http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
This driver will allow you to “see” your Block Erupters in the Printers and Devices section of the PC’s Control Panel.
3: Plug in the USB miners.
STEP 4: Note down the COM Numbers for each Device.
– In Windows (XP/7/8), go to Control Panel
– Click on Printers and Devices
– You should see USB devices or LPT COM port #:
STEP 5: Create a Desktop Shortcut.
To launch cgminer, create a shortcut with a target command line that looks like this:
C:\cgminer\cgminer-nogpu.exe -o [pool]:[port] -u [username].[worker] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM4 -S //./COM5 -S //./COM6
Notice that pool, port, username, worker and password are private credentials you provide for your pool worker.
Notice that COM3, COM4, COM5, COM6 are the COM numbers for my four miners. Yours will be different depending on what is reported in your Device Manager. You would need as many of these in your target line as you have miners.
Or you can run command line. Go to CMD or DOS, cd to cgminer directory, and run the
STEP 6: Launch CGMiner.
Launch CGMiner from the shortcut and you should see something like this: cgminer-nogpu.exe -o [pool]:[port] -u [username].[worker] -p [password] –icarus-options 115200:1:1 –icarus-timing 3.0=100 -S //./COM[usb eruptor com port #]
