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……

ThinkPad X1 Carbon 5th 原本在 Linux 下是不能使用指点杆的，很多老外都在讨论这个问题，只是一直没有解决。于是前一阵随着 X280 和 X1 Carbon 6th 开始内部测试，这个问题终于被重视了，也就被解决了。

Linux 下播放蓝光真操蛋啊……不过好歹是播放成功了，光碟是《君の名は。》日版。

Solaar is a Linux device manager for Logitech's Unifying Receiver peripherals. It is able to pair/unpair devices to the receiver, and for most devices read battery status.Install Solaar on Ubuntu can be easy with a deb file, but that's a bit out of date,many new features are not included.So I recommend to install latest version from github manually.
