preenfm2 and preenfm3 / Bought used preenfm2, usb not working properly

« on: May 27, 2017, 09:29:51 PM »

Hi everyone,

since I am no expert in assembling DIY kits I bought one used preenfm2.
I tried under MacOSX and Linux to attach it as an USB Mass storage device by pressing a key on boot and then pressing ENG but I do not see usb devices appearing.
Midi also doesn't work (I don't see the device), however the midi setting is set on Midi In/Out
So, the device is powered on but I cannot communicate with it via USB (midi or usb storage)

Do you think it is an hardware problem?

Firmware is 1.06
Bootloader is 1.11

Thanks in advance!

Cheers
