Мой кейс modbus через usb адаптер owen который на Exar XR21B1411, нужен модуль ядра kmod-usb-serial-xr_usb_serial_common, если адаптер на другом чипе то смотрим модуль на него, самый распространенный kmod-usb-serial-pl2303

[port-1]
port=/dev/ttyXRUSB0
homed управляет 2 котлами которыми в свою очередь управляет контролер https://owen.ru/product/2trm1
