Здравия! Пытаюсь в линуксе настроить работу усб портов, в первоначальном варианте не было дтб файла для этой доски, его не сделали. Для подобных плат дтб файлы позволяют загрузить систему, но не работает усб. На другой доске с таким же чипом усб заработал из коробки, оба 2, 2.0 и 3.0. Андроид дтб для неё я достал, переконвертировал в дтс, про усб у него:

Пробовал и в исходниках ядра где лежат dts вносить изменения как описано ТУТ и результат такой же, когда я редактировал дтс и приводил dmesg выше.
Что делать, куда копать?
