[solved]kernel >= 3.5.4 usb gspca webcam does not work
usb webcam (using gspca_main and gspca_stv06xx driver ) as my logitech "quickcam web"
are activated by apps like cheeze, kopete, skype
but there is a black screen instead of an image
i checked this phenomenon with 3.5.4 and 3.6.5-2
no pb with 3.16, 3.2.28, 3.4.11
i note :
during pc startup i have an error message : "no /proc/bus/usb/"
when using usbview i have an error message :
cannot open the file /proc/bus/usb/devices
verify that you have usb compiled into your kernel,
have usb core module loaded,
and have the usbdevfs filesystem mounted
in dmesg no error about any usb software component and devices "mouse, keyboard, bluetooth, webcam", all is good about usb
i have no pb with other usb devices : mouse, keyboard, bluetooth dongle, printer
there is some feature changed in the kernel thus gspca_stv06xx is no more compliant. but which one?
