Litecoin QT tuto
Install the driver (double click the .exe). Just click next in all the windows, until you can click 'finish'. Somehow the setup_x64 version did not work for me, even though I am on a 64bit windows. So if the device does not get recognized in the next step, please try to install the other setup.exe.
4 -You are getting closer! You should have a power supply now, with a power cord connected. You should also have a power cord running from the power supply to your miner. You can now plug in the USB into your miner:
Plug the other end in your computer. Make sure the USB port of your computer has enough power (if your computer does not recognize a new device, the port probably does not have enough power). I also had a problem with USB3 ports, so you should try to use a USB2 port.
7 -Check the com port. To connect to your miner, you need to know what comport is assigned to your miner. You can do this by pressing the windows key + the R key. So 'Windows + R'. This should give you a small window called 'run'.
Enter 'compmgmt.msc' in the window, and hit the enter key. This should open a new window, called 'computermanagement'.
Now click the small arrow in front of 'Ports (COM & LPT)'
Now you can see that in my case it says 'STMicroelectronics Virtual COM Port (COM7)'. This means that my miner is now assigned to COM port 7.
8 -Changing the COM port number(option, You can skip this step.). You do not need to do this. This step is only to show how to change the COM number in case you need in some situations.
Change COM number like this:
In the devicemanger, right click on the 'STMicroelectronics Virtual COM port (COMXX)', which has a COM port number above 10. Select 'properties'. This will open a new window, go to the 'portsettings' tab in that window.
Now, click 'advanced'. This will open another window, in which you can select which COM port to use. Select one that is not in use, and click 'ok' after you are finished.
Also click 'ok' in the properties window. Make sure the COM port now has the number you selected:
If all is correct, you can close the computermanagement window.
8 -Now you know your COM port number. You can setup your miner now!
10 -Edit the run.bat file. Right click on the bat file, and select 'edit', and Save the file.
10 -Mine away! Just double click the bat file. It should start a small window, and your miner will start mining. If you have more than one miner, just make a copy of the bat file, change the COM port number, and start that one as well. You need one cpuminer window per miner.
As soon as you start seeing 'yay!!!' you know that your miner is working properly. This version of cpuminer is not able to show the hashrate, so your hashrate will always show '0.00 khash/s', even though it is mining.
