How to solve it, camera works fine:
1) install:
# urpmi kernel-source-3.12.20-1.mga4-1-1.mga4 gcc make kernel-devel

2) under root edit /usr/src/kernel-3.12.20-1.mga4/drivers/media/usb/gspca/pac7302.c
in the position needs to be added the line:

/* -- module initialisation -- */
static const struct usb_device_id device_table[] = {
	{USB_DEVICE(0x06f8, 0x3009)},
	{USB_DEVICE(0x06f8, 0x301b)},
	{USB_DEVICE(0x093a, 0x2620)},
	{USB_DEVICE(0x093a, 0x2621)},
	{USB_DEVICE(0x093a, 0x2622), .driver_info = FL_VFLIP},
	{USB_DEVICE(0x093a, 0x2623), .driver_info = FL_VFLIP}, /* Genius iLook 317 */
	{USB_DEVICE(0x093a, 0x2624), .driver_info = FL_VFLIP},
	{USB_DEVICE(0x093a, 0x2625)},
	{USB_DEVICE(0x093a, 0x2626)},
	{USB_DEVICE(0x093a, 0x2627), .driver_info = FL_VFLIP},
	{USB_DEVICE(0x093a, 0x2628)},
	{USB_DEVICE(0x093a, 0x2629), .driver_info = FL_VFLIP},
	{USB_DEVICE(0x093a, 0x262a)},
	{USB_DEVICE(0x093a, 0x262c)},
	{USB_DEVICE(0x145f, 0x013c)},
	{USB_DEVICE(0x1ae7, 0x2001)}, /* SpeedLink Snappy Mic SL-6825-SBK */
	{}
};

and save.

3) Copy .config from previous MGA kernel or actual running kernel:
# copy cp /boot/config-`uname -r` ./.config

4) compile the kernel:
# make

or make -j4 (or 2, 3; depends how many Core CPU have)...

5) then
# make modules && make modules_install && make install

6) restart PC/notebook and boot to the new generated kernel

7) check modinfo and ls /dev/video*
# modinfo gspca_pac7302

# ls /dev/video*
/dev/video0

8) Skype: have to be used LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype or LD_PRELOAD=/usr/lib64/libv4l/v4l2convert.so skype

And camera works well...

NOTE: this camera can be added to gspca.txt as supported.

Can be add this modification in the next kernel update for MGA4 and Caulron?

Thank you...
