Description
Use any of the following commands to list USB devices on a Linux system. lsusb is the most concise. The dmesg commands are quite verbose, and so also usb-devices. The last three commands, lsblk, blkid, and fdisk are only relevant if you have a USB drive.
$ lsusb $ dmesg $ dmesg | less $ usb-devices $ lsblk $ sudo blkid $ sudo fdisk -l
