了解lsUSB命令

Linux使用lsusb查看USB设备信息。

安装工具：

[root@zcwyou ~]# yum -y install usbutils

1. 查看USB设备汇总信息

命令:

[root@zcwyou ~]# lsusb

输出：

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
