if insmod the module it shows error of "Required key not available", you are using a kernel which is signed Only signed module can be use in this condition.

1. Create signing keys

    openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Descriptive name/"

2. Sign the module

    sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 ./MOK.priv ./MOK.der /path/to/module

3. Register the keys to Secure Boot

    sudo mokutil --import MOK.der

	Supply a password for later use after reboot

4. Reboot and follow instructions to Enroll MOK (Machine Owner Key). Here's a sample with pictures. The system will reboot one more time.
5. Confirm the key is enrolled

mokutil --test-key MOK.der

 initial it will use USB2.0 mode which will limite 5G 11ac throughput (USB2.0 bandwidth only 480Mbps => throughput around 240Mbps)
when modprobe add following options will let it switch to USB3.0 mode at initial driver
options 8814au rtw_switch_usb_mode=1



## TODO: run time change usb2.0/3.0 mode
### usb2.0 => usb3.0
```
sudo sh -c "echo '1' > /sys/module/8814au/parameters/rtw_switch_usb_mode"
```
### usb3.0 => usb2.0
```
sudo sh -c "echo '2' > /sys/module/8814au/parameters/rtw_switch_usb_mode"
