MAYDAY MAYDAY MAYDAY

Hi. I can't find kernel module for my web cam. :(
I am using ASUS k73sm. and lsusb gives:
Code:
 Bus 001 Device 004: ID 058f:a014 Alcor Micro Corp. Asus Integrated Webcam


One manual says that i need uvcvideo but there isn't such config in the kernel.

Help, please!

PS: It seems that I chose wrong forum, sorry.

No worries. Moved from Desktop Environments to Kernel & Hardware as it fits better there.

Module uvcvideo is build with CONFIG_USB_VIDEO_CLASS which is under
Code:
 -> Device Drivers
   -> Multimedia support (MEDIA_SUPPORT [=m])
     -> Media USB Adapters (MEDIA_USB_SUPPORT [=y])

Ok. I did it. Still not working. Skype video does't work. Kernel configs:

[*] Cameras/video grabbers support
<*> USB Video Class (UVC)
[*] UVC input events device support

Code:
 ~ $ mplayer tv://
MPlayer 1.1-4.6.3 (C) 2000-2012 MPlayer Team
MMX2 supported but disabled

Воспроизведение tv://.
No stream found to handle url tv://

Выходим... (Конец файла)


MMX2 supported but disabled. hmmm... What does it mean?

I have this one in my dev.
Code:
~ # ls -l /dev/video0
crw-rw---- 1 root video 81, 0 авг.  29  2013 /dev/video0


My USE
Code:
 USE="X acl alsa amd64 berkdb bindist bzip2 cli cracklib crypt cups cxx dri fortran gdbm gif iconv ipv4 ipv6 jpeg libkms mmx modules mp3 mp4 mudflap multilib ncurses nls nptl openmp pam pcre png python qt4 readline session sse sse2 ssl tcpd udev unicode xa xcb zlib"

And which use flags are used to build mplayer?
Check especially mmxext (for mmx2 support).

The point is that skype is dubious when in comes to video on linux.
It is better first check video on some "standard" and well known software, then play with skype.

Ok. MMX2 support I already added. By mmxext USE flag. But the problem is still exists.
So now I have:

Code:
[*] Cameras/video grabbers support
<*> USB Video Class (UVC)
 [*] UVC input events device support


Code:
 ~ $ emerge --info | grep USE
USE="X acl alsa amd64 berkdb bindist bzip2 cli cracklib crypt cups cxx dri fortran gdbm gif iconv ipv4 ipv6 jpeg libkms mmx mmxext modules mp3 mp4 mudflap multilib ncurses nls nptl openmp pam pcre png python qt4 readline session sse sse2 ssl tcpd udev unicode xa xcb zlib"


Code:
~ $ mplayer tv://
MPlayer 1.1-4.6.3 (C) 2000-2012 MPlayer Team
Воспроизведение tv://.
No stream found to handle url tv://
Выходим... (Конец файла)

Add v4l/v4l2 to mplayer then run

Code:
mplayer -tv driver=v4l2:device=/dev/video0 tv://


if still won't work show
Code:
ls -lA  /dev/vid*
ls -lA /dev/v4l/*
and copy your kernel .config to pastebin.com
