lscpi 得到设备信息如下

Multimedia controller: Broadcom Limited 720p FaceTime HD Camera

据此在github找到相关驱动的项目 https://github.com/patjak/bcwc_pcie

gentoo 上的安装摘录如下：

Get Started on Gentoo
On Gentoo it is no longer necessary to extract the firmware from a running OS X. Simply use the bcwc_pcie ebuild from https://github.com/toaster/gentoo-overlay.git.

The following steps have to be performed as root.

Adding the overlay using layman
First create a local overlay list:

echo '<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE repositories SYSTEM "/dtd/repositories.dtd">
<repositories xmlns="" version="1.0">
  <repo quality="experimental" status="unofficial">
    <name>toaster</name>
    <description>toasters own ebuilds</description>
    <homepage>https://github.com/toaster/gentoo-overlay</homepage>
    <owner type="project">

    <source type="git">https://github.com/toaster/gentoo-overlay.git</source>
    <feed>https://github.com/feeds/toaster/commits/gentoo-overlay/master</feed>
  </repo>
</repositories>' > /etc/layman/overlays/toaster.xml

Then make it known to layman and add it to your local overlays:

layman -L
layman -a toaster

Install the driver
Note that you have to set the ~amd64 keyword for the driver package and for media-video/apple_facetimehd_firmware. How this is done in detail depends on how you manage your keywords.

emerge -av media-video/bcwc_pcie

The firmware ebuild will download a partial OS X 10.11 upgrade and extract the firmware from it. It is not necessary to boot OS X and extract it manually.
