* This example demonstrates how to change the USB MIDI
* device name on Seeedstudio XIAO M0.
*
* Windows and Macintosh systems often cache USB info.
* After changing the name, you may need to test on a
* different computer to observe the new name, or take
* steps to get your operating system to "forget" the
* cached info. (TODO: wanted... can anyone contribute
* instructions for these systems)
*
* This example code is in the public domain.
