- Recompilar el kernel
# make && make modules_install # cp arch/x86_64/boot/bzImage /boot/bzImage-2.6.28-gentoo-r1 # cp System.map /boot/System.map-2.6.28-gentoo-r1 # cd /usr/src # emerge -v nvidia-drivers # eselect opengl set nvidia # emerge -v vmware-modules
- Se instalan los siguientes módulos relacionados con Video y Audio
INSTALL drivers/media/video/compat_ioctl32.ko INSTALL drivers/media/video/uvc/uvcvideo.ko INSTALL drivers/media/video/v4l2-common.ko INSTALL drivers/media/video/v4l2-int-device.ko INSTALL drivers/media/video/videodev.ko

- Rearranco el equipo.
- Tras el arranque por completo verifico que los módulos de video y audio están cargados

Instalación
- No hace falta realizar ningúna instalación adicional, simplemente comprobar que reconoce la camara/micrófono una vez lo conectamos a un puerto USB libre:
# dmesg : usb 1-6: new high speed USB device using ehci_hcd and address 6 usb 1-6: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device <unnamed> (046d:0990) input: UVC Camera (046d:0990) as /devices/pci0000:00/0000:00:1a.7/usb1/1-6/1-6:1.0/input/input6 usb 1-6: New USB device found, idVendor=046d, idProduct=0990 usb 1-6: New USB device strings: Mfr=0, Product=0, SerialNumber=2 usb 1-6: SerialNumber: 2F5DA448 usbcore: registered new interface driver snd-usb-audio
# lsusb : Bus 001 Device 003: ID 046d:0990 Logitech, Inc.
Configuración
- Después la configuramos en algún programa que use video y audio, en mi caso he utilizado Skype
