Ubuntu 无法检测到 wifi/bt 组合卡 BCM4330 (AP6383)

我正在使用 Zotac pi320。在 Windows 8.1 中，内置 (sdio) wifi 卡被检测到并在详细的设备设置中显示为 broadcom 4330。二次研究证实了这一点，拆解显示芯片为 AP6383，它也对应于 BCM 4330。

在全新安装的 ubuntu 14.10 中，没有添加或删除任何其他内容，根本无法识别此设备。我仔细检查了所有输出，lspci -v但什么都没有，也没有在其他地方找到任何东西，例如网络管理器。我确实确认了 /lib/firmware/brcm/ 中存在 *.fw 和 *.bin 文件，并且存在预期的 4330 和 43xx 文件。iwconfig也没有显示此设备。我重新运行，hw-detect但没有结果。

Promethean，我尝试了大约两周，并得到了 Broadcom 和 Intel 黑客的帮助，才让它工作起来。更详细的描述位于博客文章，但要点如下：

ACPI 当前已损坏，因此 WiFi 已关闭。通过发出以下命令进行确认

# cat /sys/bus/acpi/devices/INT33BB\:00/power_state
D3cold

因此使用

# echo on > /sys/bus/platform/devices/INT33BB\:00/power/control

这就是全部了！:) 如果你需要固件，请将 brcmfmac4330-sdio.bin 从 linux-firmware 复制到

/lib/firmware/brcm/brcmfmac4330-sdio.bin

然后从 Windows 驱动程序中获取 NVRAM 文件并将其复制到

/lib/firmware/brcm/brcmfmac4330-sdio.txt

我的样子是这样的：

我让 STA 和 AP 都工作了。

电源按钮是 ACPI 问题。英特尔的 Mika Westerberg 针对 3.19 制作了一个补丁：

From 3404c6f2422c9e8d3f51a8832fbce01483c423d9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] pinctrl: baytrail: Relax GPIO request rules for certain pin

On Baytrail-T based machines the power button is part of GPIO keys like
button array (and implemented as a GPIO). However, Zotac ZBOX BIOS fails to
configure the pin properly which prevents the driver to request it.
Following is printed on the console:

  byt_gpio INT33FC:02: pin 16 cannot be used as GPIO.

Fix this by relaxing GPIO request rules for this particular pin.

这样电源按钮就可以正常工作了。Mika 说这个补丁会进入主线，但不想确认 3.20，因为这需要做更多的工作。
