Hi, I’m using a modified version of Arduino Zero Bootloader. I am trying to write software to automatically detect which USB device the bootloader is currently running on in order to execute bossac. I have noticed a few unique characteristics when using “lsusb -v”. Things like “bDeviceClass” is always 2. and “bDeviceSubClass” is always 0; However, I do not feel confident in using these traits to identify the bootloader. Is there any clear indication of bootloader so I can find the correct ttyACM#?
