lsusb
1.lsusb查看系统的USB设备
$ lsusb
Bus Device : ID : Kingston Technology
Bus Device : ID 1d6b: Linux Foundation 2.0 root hub
Bus Device : ID 0e0f: VMware, Inc.
Bus Device : ID 0e0f: VMware, Inc. Virtual USB Hub
Bus Device : ID 0e0f: VMware, Inc. Virtual Mouse
Bus Device : ID 1d6b: Linux Foundation 1.1 root hub
2.lsusb -t查看系统中的USB拓扑，类似cat /sys/kernel/debug/usb/devices
$ lsusb -t
/: Bus .Port : Dev , Class=root_hub, Driver=uhci_hcd/2p, 12M
|__ Port : Dev , If , Class=Human Interface Device, Driver=usbhid, 12M
|__ Port : Dev , If , Class=Hub, Driver=hub/7p, 12M
|__ Port : Dev , If , Class=Wireless, Driver=btusb, 12M
|__ Port : Dev , If , Class=Wireless, Driver=btusb, 12M
/: Bus .Port : Dev , Class=root_hub, Driver=ehci-pci/6p, 480M
|__ Port : Dev , If , Class=Mass Storage, Driver=usb-storage, 480M
3.lsusb -s <busid:| dev_num>查看对应USB总线上或对应设备的信息，加上-v可以查看详信息
$ lsusb -s :
Bus Device : ID 1d6b: Linux Foundation 2.0 root hub
$ lsusb -s
Bus Device : ID : Kingston Technology
4.lsusb -d只显示指定VID PID设备的详细信息
$ lsusb -d :
Bus Device : ID : Kingston Technology
5.lsusb -v查看系统中USB设备的详细信息
Bus Device : ID : Kingston Technology

6.此外/var/lib/usbutils/usb.ids还保存了很多设备商的VID信息
$ cat /var/lib/usbutils/usb.ids | grep
Kingston Technology
7.还有一个工具usbview,它用来解析/sys/kernel/debug/usb/devices并以图形的方式显示出来，但是效果并不怎么好。
8.一个类似的工具lspci，可以用于查看系统中pci设备的信息。
