- a keyboard already in bootloader mode will now be detected - if setting the keyboard to bootloader mode doesn't work, a hint will be printed on how to do so - instead of failing instantly when no keyboard is found, the script will now wait up to 60 seconds (it retries every 5 seconds, up to 12 times)
