I have strange problem. Any advice?
OS - balbes150’s Armbian (debian, server, kernel 3.14.29)
When Tone Board is connected to the VIM trough USB cable, everything works normal. But when trough GPIO, it is not detected after reboot (shutdown -r now) or even after power on if was executed shutdown command first. If i remove power cable and put it again - the Tone Board appears again.
