# How to use this kernel module
2021-02-18 13:45:30 +00:00
* 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
2020-01-24 08:20:42 +00:00
* All commands need to be run in the driver directory
2020-10-13 02:06:30 +00:00
* You need rebuild the kernel module everytime you update/change the kernel if you are not using DKMS

# USB 3.0 Support
2021-11-02 23:20:23 +00:00
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.
2021-04-28 23:40:40 +00:00
Notice: If you had already loaded the moduel, use `modprobe -r 88x2bu` to unload it first.
2021-08-09 13:56:32 +00:00
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`
2020-01-24 08:20:42 +00:00
2020-09-20 23:25:40 +00:00
# Debug
Set debug log use `echo 5 > /proc/net/rtl88x2bu/log_level` or `modprobe 88x2bu rtw_drv_log_level=5`
