Я читаю журналы загрузки по адресу /var/log, пытаясь понять, почему процесс загрузки занимает так много времени.

Я обнаружил, что система не может получить доступ ко многим usb-устройствам, но не могу понять почему.

Есть ли способ остановить Ubuntu от попыток доступа к ним?

Вот строки:

/var/log# grep -r "usb_id" .
