有人可以为我指出正确的方向，让我的外部无线棒 (TL-WN722N) 在我的 Xperia Neo (haida) 智能手机上工作吗？
到目前为止，我已完成以下操作：
- 我下载了 LegacyXperia CM11.0 源代码并配置了内核来构建 atheros 无线模块。 LX ROM 的构建成功，并且该 ROM 在我的 NEO 上运行。
- 我将 atheros 固件 (htc_9271.fw) 复制到 /system/etc/firmware
- 我安装了 atheros 内核模块（ath.ko、ath9k_hw.ko、ath9k_common.ko、ath9k_htc.ko）
- 我通过 Linux Deploy 安装并启动了 Ubuntu Trusty
- 然后我使用供电的 USB OTG Y 线将无线适配器 (TL-WN722N) 连接到手机
- 我强制 USB 配置克服 dmesg 中的“可用总线电源不足”消息（sudo su -c 'echo -n 1 > /sys/bus/usb/devices/1-1/bConfigurationValue'）
- 这触发了固件的加载，但不幸的是设备无法初始化，请参阅下面的 dmesg 输出。
如果有任何帮助，我会很高兴。多谢多谢！
这是 dmesg 输出：

答案1
您应该首先升级您的内核，并且 - 如果您不是从 Git 源升级，请在包管理器中搜索“linux-firmware”包，您需要它。我在 Android OSE、Ubuntu x86 和 arm7hf 下遇到了类似的问题 - 所有这些问题都通过执行我提到的操作来解决
