[SOLVED] Cannot load firmware, flipper visible only in DFU mode - Debian


I have made this topic just to share my solution with anyone still having troubles with connecting to FlipperZero. Please make sure you have cdc-acm module loaded (# modprobe cdc-acm). Otherwise /dev/ttyACM0 will be missing and qFlipper will try to connect using any of /dev/ttyS* devices (and then it will fail).


I’m adding a hashtag so I can find this later if I need it. Thanks for sharing!
