Como dice el titular, tengo una pregunta sobre este fenómeno. Cada vez que conecto una memoria USB aleatoria a un puerto USB aleatorio de mi computadora portátil Linux, mi impresora comienza a mover su interior. Esto sucede cada vez que la conecto. Tengo una computadora diferente en la misma red que ejecuta Windows 10, sin embargo, no le sucede nada a la impresora cuando conecto una memoria USB en esa máquina, ni a ningún otro dispositivo que haya probado. Además, esto sucede en el momento en que lo conecto, incluso antes de escribir el comando de montaje. ¿Alguien puede iluminarme sobre este comportamiento? Parece muy extraño.
Este resultado se toma directamente de journalctl:
Command: journalctl --since "2019-06-28 15:00:00"
-- Logs begin at Sun 2018-01-28 16:58:17 CET, end at Tue 2019-05-28 17:44:19 CEST. --
-- No entries --
Esta es la salida de dmesq después de conectar y desconectar un USB varias veces:
