maybe this is what you’re looking for

SETUP – WINDOWS

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 .
