Здравствуйте.
Просьба помочь разобраться с USB WiFi устройством Comfast CF-953AX.
Используется чип MediaTek mt7921au.
Заявлена поддержка с ядра 5.18 в модуле mt7921u.
У нас на ядрах un-def по какой-то причине модуль не собирается. Смотрел на 6.1.71, 6.1.72 из p10 и 6.6.11 из сизифа.
Ядро его видит, определяет. Выключал usb_modeswitch для проверки - без изменнеий.

Bus 002 Device 002: ID 0e8d:7961 MediaTek Inc. Wireless_Device
Пересобрал ядро, модуль появился.
modprobe -v mt7921u
