Please try v3.3 and reboot. Thank you!

I found the issue. I'm having the same thing. It's DKMS not updating the new module with the one from the kernel. This results in loading the old module from the kernel and you can verify that if you see your distro key running modinfo huawei-wmi after installing this module.

You could build it manually and move it to /lib/modules/$(uname -r)/updates/. Or downgrade to DKMS <= 2.6.1

Build from source works! Thanks for your attention.
