Detect USB Devices – Find USB Device Name

The most common USB ports and USB flash drives work according to the USB 2 standard. Booting from USB 2 from a live drive is faster than from a corresponding CD/DVD disk. Standard USB 2 flash drives have rather slow flash hardware, with read and write speed much slower than the transfer speed of USB 2, so it is worth checking if the speed is. Download the Ubuntu image for your device in your `Downloads` folder Insert your SD card or USB flash drive Identify its address by opening the 'Disks' application and look for the 'Device' line. If the line is in the /dev/mmcblk0p1 format, then your drive address is: /dev/mmcblk0.

1. fdisk

fdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive using a menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space for new operating systems, and copying data to new hard disks. fdisk prints the partition table including any USB drive if present:

sudo fdisk -l

UsbLinux show usb ports

The argument -l, –list shows the partition table on the specified device and exits. If there is no device specified, lists the partition tables on all detected devices. Another argument -s, –size=DEVICE prints the size of the partition on DEVICE is printed on the standard output.

2. dmesg

dmesg is used to examine or control the kernel ring buffer. The default action is to display all messages from the kernel ring buffer.
dmesg is an important command that prints or controls the kernel ring buffer, a data structure which stores information about the kernel’s operations.

lsblk is another command to find the USB device name. The lsblk command lists all the block devices that are attached to the system. lsblk lists information about all available or the specified block devices. The lsblk command reads the sysfs filesystem and udev db to gather information. The command prints all block devices (except RAM disks) in a tree-like format by default. Use lsblk –help to get a list of all available columns.

lsblk

If you want to list empty devices also, run the command with -a, –all argument. By default the lsblk command doesn’t show empty devices.

You can also use df command to check the Linux disk space utilization alongwith the device name. df displays the amount of disk space available on the file system containing each file name argument. If no file name is given, the space available on all currently mounted file systems is shown.
