最近用一加五发现了一个毛病，那就是插上去后用 USB 调试模式，adb devices 之后，列表里没了！
尝试了各种方法，就是不能在 adb devices 里找到那个手机啊！

ASUS Xonar U7 MK II
我在快三年前（我操原来都这么久远了？）买过一个 ASUS Xonar U7 的声卡，用来外接笔记本 Dock 的情况下音频输出。
然后这不是三年后了么，那个声卡开始有了点小毛病。
大概毛病就是经常会供电不足设备起不来，插上去不认，反复插拔好多次后偶尔有机率导致可以使用，最后我受不了每天电脑拿回家都要插拔半天，选择了再换一个。
我的要求有三个：
1，USB 供电，我不想插电源了
2，有音频输入
3，解码芯片不能太烂
4，有耳机输出接口
找来找去那么一堆国产 DAC，发现都不能满意，最麻烦的就是没有音频输入，也不能 USB 供电，都要给你拖个大电源……
