How to get USB Block Erupters working on a USB Hub

These are destructions for getting your USB Block Erupters (Bitcoin Miners) working with a USB hub.  I'm currently running 6 block erupters on one hub with 2 more due in Friday.

STEP 1

Install CGminer 3.1.1 CGminer 3.1.1 According to my research, this is the newest version that will work with block erupters.  IF you try any newer version, CGminer won't even see them.

STEP 2

Install these drivers.  These drivers will allow your computer to "see" the block erupters.  In Windows 7/8, this will be in your "Devices and Printers" section in the control panel.  Note the COM numbers denoted by COM##, you'll need to know this later.


STEP 3

Plug in the miners if you haven't already done so.  You should hear the standard USB "device connected" sound.  From the research I've done, the Anker Hub seems to be the best hub to get.  It has enough power to power multiple miners.  It's pricier than most, but it will run 9 or 10 miners.

STEP 4

Create a new shortcut that looks like this:

C:\CGMiner\cgminer-nogpu.exe -o pool:port -u username -p password --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM9 -S //./COM12  -S //./COM21 -S //./COM20 -S //./COM19 -S //./COM22

This one is for my computer's COM ports.  You'll have to plug in your own info in regards to the pool, username, password, and any additional (or less) "-S //./COMXX flags.  This shortcut is also setup for 6 miners, denoted by the 6 different COM ports.

STEP 5

Run your CGminer Shortcut!  Then you should see something like this:

OTHER INFO

Don't plug your hub into a USB 3.0 port. It won't work. Works fine with USB 2.0.

Only use CGminer 3.1.1.

The USB hub of choice seems to be the Anker 10 Port USB 3.0 Hub

Might not hurt to get a USB Fan.
