Через OPKG пробуем запросить smart, первый вызов отрабатывает, на следующий раз - роутер зависает и не доступен пока не отвалится накопитель:

smartctl -d sat,12 -a /dev/sda

Хотелось бы полноценной поддержки для накопителя, где заявлено:

• USB 3.0 gen 1×1 interface with type-A connector
• USB Attached SCSI Protocol with fallback to USB Mass Storage
• USB 3.0 U1/U2 idle power saving support
• SMART drive health reporting

Спасибо. 

P.S. Отключение dev.usb.allow_uas решает проблему, но только вот Pi OS не "падает" (зависает и не обрабатывает трафик/не открывается интерфейс) от этого накопителя в любом режиме, как и любой другой линукс, например,  на Radxa E52.
