我在这里有一个连接了很多 USB 设备的设置，这是我的lsusb输出：

如您所见，有多个相同的设备和多个具有相同供应商 ID 的集线器。我正在使用 Wireshark（实际上是 tshark）监控这些，我得到一些像这样的错误：

293549  43.514117       3.17.1 → host         USB 66 URB_BULK in[Malformed Packet]

但是，如果没有设备的序列号，我无法从物理上识别它是哪个设备。

我可以在 dmesg 上看到这个序列号

[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: New USB device found, idVendor=16c0, idProduct=05dc
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: Product: USB BDC
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: Manufacturer: www.engineeredarts.co.uk
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: SerialNumber: 345B34673238

我的问题是：我怎样才能匹配这两个东西？或者至少，dmesg在我从 tshark 获得的数字中，我怎样才能获得相同的“序列号”？

（在观看 dmesg 和 lsusb 时重置每个设备以查看哪个设备不是一个选项）

知道了！原来你可以用sudo lsusb -v. 它必须以 root 身份运行，否则文件将为空，然后要清理所有无用的信息，请执行如下快速 grep 操作：

lsusb -v | grep '^Bus\|iSerial'

这是 grepping 2 个结果（由 OR 运算符分隔的 \| 分隔），第一个是用单词 Bus 开始（^）的东西，第二个是它包含单词 serial

还偶然发现了另一个我不知道的命令：
