MicroFreak USB connection for PC Win7

I’ve found a really working way how to connect MicroFreak to a PC to be able to upload samples and presets to it!
It did worked on two neighbour USB ports on the front panel. One 2.0 another is 3.1
The key thing is that you need to run MIDI Control Center (1.16.2.79 is for Win7) before connecting your MicroFreak to a USB port. You need to go to View and check “MIDI console” in MCC. This version doesn’t have options to save this so it’s necessary to check it every time.
Somehow… showing this console in the program doesn’t allow MF to be thrown out from the USB connection (maybe you know better words, English is not my native language). I’ve checked this dependence few times just few minutes ago.
It doesn’t works from my old USB hub which I connect to a USB extending cable.

Noo… I’ve thought that I’ve found it!
Now I’ve slightly changed conditions and it’s not that easy again.
Digging further…
Update: it works… Kind of. If you connect a 12v 1A (or more amps) PSU to MicroFreak 's power input. Probably at some moment it draws more current than usually needs. But it’s not the solid rule.
Check the polarity if the PSU is not from this synth! It’s a usual rule but sometimes ignoring it leads to a broken gear. Be careful!
