Установка драйвера Bluetooth для EP-AC1661

Я использую адаптер Bluetooth и EP-AC1661 WiFi. Согласно их веб-сайту драйвер поддерживается только для версии 2.6 ядра.I, пытаюсь установить драйверы на человечности 18.04 с 5.0.0.29-универсальной версией ядра

когда я выполняю команду

sudo make install -s

Я получаю ошибку

    rtk_coex.c:2532:2 :error: implicit declaration of function 'init_timer'; did you mean 'init_timers'? [-Werror=implicit-function-declaration]
init_timer(&btrtl_coex.polling_timer)

какие-либо указатели в том, как я устраняю эту проблему?
