Для правильной работы драйверов
libfprint, нужно чтобы мой тачпад был виден в lsusb, но его там нет.
Нужно мне это для работы моего сканера отпечатка пальцев. Я смог заставить выдавать рисунок моего пальца с помощью этого проекта
elan-spi-fingerprint , но для сборки драйвера libfprint, нужно наличие устройства в lsusb.
Устройство ELAN дает знать о себе если глянуть в xinput list:

Если конкретнее, то мне нужна видимость устройства с адресом 04F3:241F (именно с этим адресом я и смог получить скан своего пальца)
