What happened ?

name just shows up in Mac OS MIDI setup as ' pico', USB info does show the correct name and manufacturer

How to reproduce ?

run the code look at audioMIDI setup on Mac and then see USB names in System Report

Debug Log

No response

Screenshots

No response

USB info does show the correct name and manufacturer

What happens if you change the VID and PID? Sounds like Mac OS MIDI may recognize the combo of the two and is applying it's own name to it. The library can't control what applications do with the information the device provides.

I don't see how to change the VID/PID. However, if I delete the device in OSX Audio MIDI utility then replug it, it seems to be working now. I'm sure I tried this before but got no result..

could you update 1st post to

1. provide the arduino core (BSP) version
2. remove sketch code and attached it as txt file instead.
3. also try to run the stock example midi_test to see if that works

[steeley]

done. I think replugging does update the USB descriptor. It may only be an issue if you keep changing the descriptors on the same board, then sometimes the OS doesn't immediately update the USB name.

[hathach]

host driver always do its own caching for fast enumeration and driver mapping usually with vid/pid/bcd combo

USBDevice.setManufacturerDescriptor( My_Manufacturer);

USBDevice doesn't even compile on the midi_test example It reports as not declared. At least when compiling for the LOLIN S2 MINI board. I try to use "TinyUSBDevice" instead, but it does not work. There is a bug somewhere in my opinion.
