It was with firmware on it and was working
I have downloaded bootmapper client and all ok connecting lights etc. But I have pressed the bootloader button and after that nothing. It was not connecting and showing msg: Cannot find HID device or something like this. Tried to set it up as USB, but nothing still the same. This is the first time I'm using bootmapper. did this as I want to see if this pcb is supporting ISO format 
Some help will be highly appreciated
