Re: Wii: bwi driver fails to attach for device id 0x044b on NetBSD 11.0-BETA

Hi!

That's interesting, I haven't been able to reproduce this myself with any 
of the NA units that I have, but after seeing your message I went back 
and looked at Jun Ebihara's dmesg from 
https://mail-index.netbsd.org/port-powerpc/2025/06/16/msg003701.html 
and the same error is there.

Maybe a different wifi chip in some revisions of the device?

For a quick test, can you build a kernel with the following hack to see 
if it helps?

The driver detects the device but reports “no BBP id for device id 0x044b” and, as expected, I only see the loopback adapter lo0. I suspect this may be a hardware revision not present in the driver's table. If that’s the case, is it possible to add support for this device?
