I guess you should also take a look at
Device Drivers > Multimedia support > Media USB Adapters

e.g.
MEDIA_USB_SUPPORT
MEDIA_CAMERA_SUPPORT
MEDIA_CONTROLLER
...

You need UVC-Support:
CONFIG_USB_F_UVC=3Dy

I'm using kernle: linux-3.10.7
but there is no CONFIG_USB_F_UVC setting, I can not find anything for UVC
grep UVC .config
I get empty line.

I have fond setting in kernel 3.10 for UVC

grep USB_VIDEO_CLASS .config
CONFIG_USB_VIDEO_CLASS=3Dy=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0(USB Video Clas= s (UVC))

but I still don't see the USB camera in skype.

Do yo= u have these enabled and set?

grep '^CONFIG.*V4L' /usr/src/l= inux/.config
CONFIG_VIDEO_V4L2=3Dm
CONFIG_V4L_PLATFORM_DRIVERS=3Dy
CONFIG_MEDIA_SUPPORT=3Dm
CONFIG_USB_VIDEO_CLASS=3Dm
CONFIG_USB_= VIDEO_CLASS_INPUT_EVDEV=3Dy
CONFIG_USB_GSPCA=3Dm
CONFIG_MEDIA_PCI_SUP= PORT=3Dy

grep -s ^LD_PRELOAD .*
.bash_profile:LD_PRELOAD=3D/usr/l= ib/libv4l/v4l2convert.so

Also, you = may want to try plugging you webcam into a USB2 port, if available, instead= of a USB3 one, as suggested here, http://linux-kernel.= 2935.n7.nabble.com/3-15-8-USB-issue-with-uvc-cam-td920378.html.

Hope this helps.
