Проблемы с Klipper-ом

Попытался запустить KLIPPER - все по инструкциям с этого сайта.

Все прошло без проблем, установил клипер на orangepi, под пользователем dsi, под ним же крутится octaprint и без проблем подключается к марлину через /dev/ttyUSB0, зашил атмегу клиперовским firmware (у меня mega 2560 + Ramps 1.4)

Но итог таков: не видит клипер принтер - не подключается и все. Ребутил ось, ребутил железо принтера.... перепрошивал никакого результата!

Может кто сталкивался с подобным?

Вот логи клипера:
