USB is only good for power supply

Hi, my PreenFM2 doesn't show in any of 3 computers (win7 win10 and Linux Ubuntu) neither as Midi interface or as USB stick when it boots with button 1 pressed.
However it powers ON and works with USB power.
I built it and flashed its bootloader to v1.11 a few months ago with the mini-usb.

I've try with several USB Cable and USB-midi is turned on in system.
Running firmware 2.07.

Any clue?

Hi,

Is the USB midi enabled ?
See 3.1 here, first setting :

I just realized you wrote "Mini-USB" ?
So you have a CERB40 cpu board ?

You need a wire to link the case USB to the CERB40 mini USB.
Search for CERB40 in this old-PCB page :

Doh!

I thought it was only used to flash the bootloader....
