Q1. I do not understand why step 3 is necessary.
Q2. If the step 2 is used for flash, how can I change /dev/ttyACM0 to /dev/ttyUSB0 for west flash?
Q3. If step 3 is not relevant to west flash, what is wrong with the above procedure?
I don't have this board, and I can't help you with Q1 or Q3, but for Q2:
you can always run this command to get help on options that are
available to you:
$ west flash --context -d <YOUR_BUILD_DIR>
In this case, you are looking for the --bossac-port option.
Best,
