Bir sdcard okuyucuya takarken neden linux kızılötesi sürücüleri yüklüyor?

Bir Modecom CR-202 kart okuyucum var. Bu Realtek'tir (VID = 0bda, PID = 0161).

Bu donanımın IR ile ne ilgisi var? Dmesg'in çıktısının ortasına bak.

Görünüşe göre en azından USB ID ile tanımlanan bazı cihazların 0bda:0161kızılötesi bir arayüzü var. Örneğin, bu e-posta listesi kaydı, lsusb -vvçıktıda şu şekilde görülen bazı “MCE uzaktan kumandalı realtek akıllı kart okuyucusu, ön tarafta usb ve sd / cf / sim okuyucu” anlamına gelir :

Bu cihazda üç arayüz vardır: akıllı kart okuyucusu (SIM kartlar için kullanılır), toplu depolama (flash bellek kartları için kullanılır) ve “eHome Kızılötesi Alıcı”.

Cihazınız aynı yongayı kullanıyor olabilir, ancak kızılötesi kısmı üretici tarafından bağlanmadan bırakılmıştır.
