# How to use this kernel module
|
|
* Ensure you have C compiler & toolchains, e.g. `build-essential` for Debian/Ubuntu, `base-devel` for Arch, etc.
|
|
* Make sure you have installed the corresponding kernel headers
|
|
* All commands need to be run in the driver directory
|
|
* You need rebuild the kernel module everytime you update/change the kernel if you are not using DKMS
|
|
|
|
|
|
## Manual installation
|
|
### Clean
|
|
* Make sure you cleaned old build files before builds new one
|
|
```
|
|
make clean
|
|
```
|
|
|
|
### Building module for current running kernel
|
|
```
|
|
make
|
|
```
|
|
|
|
### Building module for other kernels
|
|
```
|
|
make KSRC=/lib/modules/YOUR_KERNEL_VERSION/build
|
|
```
|
|
|
|
### Installing

```
|
|
git clone "https://github.com/RinCat/RTL88x2BU-Linux-Driver.git" /usr/src/rtl88x2bu-git
|
|
sed -i 's/PACKAGE_VERSION="@PKGVER@"/PACKAGE_VERSION="git"/g' /usr/src/rtl88x2bu-git/dkms.conf
|
|
dkms add -m rtl88x2bu -v git

# USB 3.0 Support
|
|
You can try use `modprobe 88x2bu rtw_switch_usb_mode=1` to force the adapter run under USB 3.0. But if your adapter/port/motherboard not support it, the driver will be in restart loop. Remove the parameter and reload the driver to restore. Alternatively, `modprobe 88x2bu rtw_switch_usb_mode=2` let\'s it run as USB 2 device.
|
|
|
|
Notice: If you had already loaded the moduel, use `modprobe -r 88x2bu` to unload it first.
|
|
|
|
If you want to force a given mode permanently (even when switching the adapter across devices), create the file `/etc/modprobe.d/99-RTL88x2BU.conf` with the following content:
|
|
`options 88x2bu rtw_switch_usb_mode=1`
|
|
|
|
|
|
# Debug
|
|
Set debug log use `echo 5 > /proc/net/rtl88x2bu/log_level` or `modprobe 88x2bu rtw_drv_log_level=5`
