Asus RT-AC56U (BCM4708). Attended sysupgrade to 22.03.2 from 21.02. The uas module was part of the image and was unable to read the quirk from etc/modules.d/usb-storage.
So I did a custom image without usb-storage modules and then installed all usb storage modules using opkg. Now it reads the quirk file and works as expected.
BTW The speeds are better than USB 2 but slower than 21.02 on USB3. Exact same hardware.
Bus 001 Device 002: ID 0080:0578 JMicron External USB 3.0
Is this a bug or expected behavior?
