no interface for mt76x2u wifi card

[zebul666]

so I have a netgear A6210 usb wifi card
No interface is showing up on kernel 6.6.10/11 on rpi3b (or rpi2)
It's fine in 6.1.66 (only tested on rpi2) but it's expected to work on 6.1.66 on rpi3b too, because it was working before some time ago...

Are you using the linux-rpi kernel package? It should be providing that module:
[code]
% pacman -Ql linux-rpi|grep mt76x2
linux-rpi /usr/lib/modules/6.6.11-1-rpi-ARCH/kernel/drivers/net/wireless/mediatek/mt76/mt76x2/
linux-rpi /usr/lib/modules/6.6.11-1-rpi-ARCH/kernel/drivers/net/wireless/mediatek/mt76/mt76x2/mt76x2-common.ko.xz
linux-rpi /usr/lib/modules/6.6.11-1-rpi-ARCH/kernel/drivers/net/wireless/mediatek/mt76/mt76x2/mt76x2u.ko.xz
[/code]

oh yeah the module is loaded. but no interface

If it worked under the 6.1.y series but not under the 6.6.y series, recommend you open an issue against the kernel package. Let's see what upstream has to say:
make_clickable_callback(MAGIC_URL_FULL, '
', 'https://github.com/raspberrypi/linux/issues/new/choose', '', ' class="postlink"')

Do you see any errors in journalctl output?

the last 2 lines are weird. I thought it was related to a pl2303 usb device (a temp probe) but this happens without it and with the wifi card only
and this happens on 2 rpis. so not the usb hub

make_clickable_callback(MAGIC_URL_FULL, '', 'https://github.com/raspberrypi/linux/issues/5851', '', ' class="postlink"')

someone told me "sounds like a defconfig/dtb issue" on #raspberrypi if it means anything to you

[zebul666]

It seems either nobody noticed the issue on their github or noone cared about it...
