There are many programs and many ways to list USB devices on Linux:

To display information about USB devices connected to your system, you can use the lsusb command.
$ lsusb

To display detailed information about each device, use the -v option.
$ lsusb -v

To display the device list as a tree so you can see what devices are connected to what controllers, use the -t option.
$ lsusb -t

You can run the following command to list all the connected USB devices of your system:
$ usb-devices

If you want to list all the USB block storage devices, that is all the USB storage devices, then you can use the lsblk or fdisk command to do so.
$ lsblk

You can get almost the same information as lsblk command with blkid command. But you have to run it as root as follows:
$ sudo blkid

You can also use fdisk command to list all the USB block storage devices.
$sudo fdisk -l

You can use the dmesg command to find out more information about the connected USB devices.
The last connected USB device is the easiest to find with dmesg command.
It is more widely used for debugging purpose. In short the output of dmesg command is system log messages.
$ dmesg

Almost everyone uses some type of USB devices in their System.
These days there are
USB webcams,
USB hard drives,
PenDrive etc.
Almost every device has a USB version of it. Listing what USB device is connected to your system might be necessary at some point when you’re using Linux.
