Linux: How do I list all USB devices?

Q. How do I list all USB devices connected to my computer / Linux laptop?

A.You need to use command called lsusb. It is a utility for displaying information about USB buses in the system and the devices connected to them under Linux kernel.

lsusb – list USB devices

To make use of all the features of this program, you need to have a Linux kernel which supports the /proc/bus/usb interface (e.g., Linux kernel 2.3.15 or newer).
$ lsusb
Output:

Bus 004 Device 002: ID 0930:6532 Toshiba Corp.
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

To get verbose output type the command:
$ lsusb -v
