A 0 azt jelenti, hogy nincs?
sudo modprobe uvcvideo  – a terminálablakban lefuttatva nem történt semmi.
A cheese mindenesetre azt írja ki, hogy nincs elérhető kamera…

A kamera bedugása után meg kéne vizslatni a dmesg végét, hogy mihez kezdett a modullal és az eszközzel.

Ez lett az eredmény (kb. a vége…):

A cheese érzékeli a kamerát, csak a kamera által adott képet nem… 🙁
Ha pl. állítok a felbontáson, akkor meg le is fagy.
Megpróbálom egy másik progival, hátha.
