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.
Debug
Set debug log use echo 5 > /proc/net/rtl88x2bu/log_level
or modprobe 88x2bu rtw_drv_log_level=5
