Re: rpi cm4 + waveshare mini base board B stops after kernel load

When I try the recent image 2024-07-16-netbsd-raspi-aarch64.img, I am
now able to boot the kernel to the login prompt,
but key presses from my Apple USB A1243 keyboard are not recognized.

What steps do I need to perform regarding: "To use USB, set UEFI+FDT"?

I tried setting Device Manager ->  Raspberry Pi Configuration ->
Advanced Configuration -> System Table Selection -> ACPI + Devicetree,
and my keyboard works prior to loading the kernel (Raspberry Pi splash
screen and boot countdown timer).  But not after.
When I tried setting it solely to "Devicetree" as specified in this
post: http://mail-index.netbsd.org/port-arm/2022/10/03/msg007875.html
I get a kernel load hang with hex code 0x15e9d38.

Is there something else in the Raspberry Pi config screen I need to
set, or perhaps config.txt?
I understand .dtb files and overlays; I simply need a nudge in the
right direction.
