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. # Debug Set debug log use `echo 5 > /proc/net/rtl88x2bu/log_level` or `modprobe 88x2bu rtw_drv_log_level=5` # Distribution * Archlinux AUR https://aur.archlinux.org/packages/rtl88x2bu-dkms-git/
