Hello,
I tried to test WWAN mPCIe card MC7354 in IHC3308GW.

Running full Ubuntu image, it can recognize the card, but no serial AT tty device, I tried to rebuild kernel with firefly-rk3308b_docker_defconfig but with that new kernel the MC7354 is not recognized anymore (lsusb command).

So could you please help:
- Which kernel config is using in bundle Ubuntu image ?
- How to change kernel config options to enable MC7354 card ?

Thank you.

The current usb driver does not support MC7354, please contact the production MC7354 to provide usb driver.

Could you please show the kernel config using in FW IHC3308GW-Ubuntu18-NoUi-20220106.img ?

- If I do flashing whole FW IHC3308GW-Ubuntu18-NoUi-20220106.img, MC7354 is recognized well

- If I rebuild kernel using firefly-rk3308b_docker_defconfig then lsusb does not show MC7354 card anymore.

cd rk3308-linux/kernel
make ARCH=arm64 firefly-rk3308b_docker_defconfig
make ARCH=arm64 rk3308b-roc-cc-plus-amic_emmc.img


Flash zboot.img to board
