I want to circle back to the motivation for starting this thread.

I have a BeagleBone Black that boots NetBSD fine.  However, it is not detecting anything in the USB port.  For example, connecting an SD card either prior to booting or after booting during runtime leads to no storage medium being detected.  In contrast, a NetBSD/amd64 machine, laptops, cameras, etc. detect the very same card.

This led me to think that something was off with the device tree files, the kernel config, or the device probing.  From this thread, it seems that there should be no need to include a USB storage device in the device tree files, and the GENERIC kernel config does include them.  Thus, from that I would have expected the USB storage to be detected by the kernel.  I am now at a loss regarding where to start.

I have attached the kernel message buffer (from a boot with the USB storage already installed) in hopes that someone can provide advice on where to start tracking this down.  I have all the firmware properties from ofctl as well, but that is quite lengthy so I’m leaving it until someone thinks it might be useful.

I would greatly appreciate help with this or pointers regarding more information that would be helpful.

Thanks a lot.

Cheers,
Brook
