You mean b6 image? I have found unplug and replug USB device when it went to setup screen helps with detection.
I am speaking only of vendor-provided aarch64 images, not customized radxa/cix stuff. It was said earlier that ACPI mode should work (obviously without special devices) on the latest upstream kernel. So far that doesn’t appear to be the case, or that 0.3.0-1 firmware release is not there yet.
