Ubuntu没有检测到wifi / bt组合卡BCM4330（AP6383）
我正在使用Zotac pi320。 在Windows 8.1中，检测到buit-in（sdio）wifi卡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，也对应于BCM 4330。
在ubuntu 14.10的全新安装中，没有添加或删除任何其他内容，根本无法识别此设备。 我倾注了来自lspci -v所有输出，没有任何东西，在其他任何地方都没有找到，例如，网络管理员。 我确实在/ lib / firmware / brcm /中确认了* .fw和* .bin文件的存在，并且存在预期的4330和43xx文件。 iwconfig也没有显示此设备。 我没有结果重新运行hw-detect 。
Promethean，经过大约两周的尝试并得到broadcom和英特尔黑客的帮助，我得到了它的工作。 更详细的描述在博客文章中 ，但这里是要点：
ACPI目前已损坏，因此WiFi已关闭。 通过签发确认
# cat /sys/bus/acpi/devices/INT33BB\:00/power_state D3cold
所以启用它
# echo on > /sys/bus/platform/devices/INT33BB\:00/power/control
多数民众赞成真的需要！ :)如果您需要固件，请将linux-firmware中的brcmfmac4330-sdio.bin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
我看起来像这样：

我让STA和AP都工作了。
电源按钮是ACPI问题。 英特尔的Mika Westerberg创建了针对3.19的补丁：
From 3404c6f2422c9e8d3f51a8832fbce01483c423d9 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Wed, 11 Feb 2015 17:21:18 +0200 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.

这使电源按钮工作。 Mika说这个补丁会使它成为主线，但不想确认3.20，因为它需要更多的工作。
