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

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

    Hi there, how would I go about determining the port number of a specific USB device?

    with an older zonet bluetooth dongle not showing in lsusb or errors in dmesg how can I tell if there are any interactions when plugged? (Mint 15 64bit mate)

    If the device has been formatted and given a path on the system, then typing “df” will show the device/path on the list. If you unplug it and type “df” again, then compare the two lists, you can see which one it is.
