Lets stick to Chrysalis for now.

Since you’re on Linux, can you try installing the udev rules at [Chrysalis/60-kaleidoscope.rules at master · keyboardio/Chrysalis · GitHub](https://github.com/keyboardio/Chrysalis/blob/master/static/udev/60-kaleidoscope.rules) ?

Just copy the contents of those to `/etc/udev/rules.d/`, and reload the rules with `sudo udevadm control --reload-rules`.

My suspicion is that you may have permissions to write to `/dev/ttyACM*`, but no permission to write to the DFU device when the keyboard is in bootloader mode.
