[solved]kernel >= 3.5.4 usb gspca webcam does not work

since kernel 3.5.x

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?

this pb occurs with mageia 3 a3, rosa 2012.1 b1 also

i found that if you get the gspca modules sources from debian wheezy
compile and install them with your debian wheezy then it works with kernel >= 3.5

see comment 3 here

is there anyone who knows how to :

get the debian wheezy sources of gspca modules ?

unpack the .deb to get teh source in a folder ?
