got it working: - you have to use "#define USB_SUPPORT_USER_STRING_DESC" in the stm32f4 usb driver - set string indexes in the jack definition correctly - and implement the "GetUsrStrDescriptor" callback. now I have consistent and custom device names for each midi jack.

I don't want to change the interface name, but the device name. And no, the KORG does not have drivers that take care of that.

Hi, libportmidi shows the port-names as: found in device 'Midi Through Port-0' with interf 'ALSA' found out device 'Midi Through Port-0' with interf 'ALSA' while OSX shows them as: found in device 'USB-MIDI-Gerät' with interf 'CoreMIDI' found out device 'USB-MIDI-Gerät' with interf 'CoreMIDI' How can I customize the Port names ? I have a KORG NanoKontroll and it has custom (and consistent) port names on Linux and OSX. thank you! Sebastian
