An AM4 system, Ok.

You don't need to turn on power to the USB ports, they should work without any need to enable power to them. Why would a mother board manufacture configure the USB ports to be turned off by default?

Have you changed any settings in the UEFI/BIOS?

How could you update the UEFI/BIOS if the keyboard and mouse were not working?

I even upgraded BIOS to 2.6 but nothing improved.  I used http://www.asrock.com/microsite/win7install/ patcher but it didnt help as well. Can you advice me what to do?

You are using the wrong Windows 7 patcher. The link you posted above is for some Intel systems only, as it shows in the title at the top of that page.

The Windows 7 patcher for AM4 is listed in the Windows 7 download page for your board:

As said above, use the USB 2.0 ports on the IO panel. Something does not make sense here, what keyboard and mouse are you using?
