Driver for webcam: different behaviour with USB and USB via ExpressCard
by SuSE_Lamer from LinuxQuestions.org on (#5SY7H)
Hello,
unfortunately, I am not very familiar with kernel interna if Linux, therefore I have one question to experts: is it possible that one driver (UVC, to be more precise) is not loaded when I plug my web-cam via "ordinary" USB port on my laptop, but is loaded when I plug my web-cam via ExpressCard-based USB-hub?
Here is my situation: I have web-cam (Hercules DualPix Chat and SHow), which is supported by "uvc" driver. When I plug it via USB port, it does not work. But it works, when I use USB-3.0-hub in ExpressCard-slot.
Thanks in advance,
Andrey
