sorry about that, I dont know them myself, i tried to find something useful but i dont know if it is:


maybe this is what you’re looking for


The device is very easy to setup but the lack of overall instructions is quite scary. According to various sources, you need to follow the following steps:

  1. Plug in the Antminer U2 into a free USB slot that provides 500mha (so if you have a hub it’s going to need to be powered and provide that to each port)

  2. If you are running windows you are going to need to download a driver to use. This guide assumes the usage of BFGMiner so if you’re not using this miner you are on your own. The driver recommended is http://www.silabs.com/Support%20Documents/Software/CP210x_VCP_Windows.zip

  3. Unzip the folder and install either the 64bit or 32bit version depending on your version.

  4. Download BFGMiner http://bfgminer.org/

  5. Unzip the BFGMiner into a directory of your choosing

  6. Create a new BAT file using the following line:

    a. bfgminer.exe –set-device antminer:clock=x0781 -o [INSERT POOL HERE] -u USERNAME_WORKER -p PASSWORD -S antminer:all

  7. You can customize the clock speed using the following guide:

    a. 0581 =1.2GH/s
    b. 0681 =1.4GH/s
    c. 0781 =1.6GH/s
    d. 0881 =1.8GH/s
    e. 0981 =2.0GH/s
    f. 0A81 =2.2GH/s

    9. Profit!

Well I succeed to make them work on pc usb ports, but hub doesn’t recognize the devices.

Which hub are you using? Is it providing enough juice?

I use AmazonBasics Hub with 4 ports ,and it has enough juice,it just doesnt recognize the devices .
