Finally I finished mounting my pedalboard! It took a few hours. I found that a USB wire was very very short... So I placed a laptop on the ground near to a pedalboard and connected. I did steps that from instruction and then I heard first sounds! It was so exciting... Especially because I mounted it myself in general. I played with my hand, because I was so impatient to know did I mount everything correctly, is it working in general. And sorry for a quite bad quality of video...
