How do I know the device path to an USB-stick?

Solution 1:

First plug in your USB-Stick.
Then type:

lsblk

Your output should look something like this

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465,8G  0 disk 
├─sda1   8:1    0  74,5G  0 part /
├─sda2   8:2    0 390,2G  0 part /home
├─sda3   8:3    0     1K  0 part 
└─sda5   8:5    0     1G  0 part [SWAP]

Now you can use the size to determine which one is your usb stick . To mount it somewhere in your home folder for example just type:

mkdir ~/UsbStick
sudo mount /dev/PATH_TO_YOUR_STICK ~/UsbStick

obviously replacing PATH_TO_YOUR_STICK with the right /dev/sdX path and ~/UsbStick with the directory you created using the mkdir command

Solution 2:

find device path, LABEL, UUID and TYPE of block devices with help of command

sudo blkid

result will be like

/dev/sda1: UUID="XXXX" TYPE="ntfs" 
/dev/sda5: UUID="XXXX-XXXX" TYPE="ext4"
/dev/sda6: UUID="XXXX-XXXX" TYPE="swap" 
/dev/sda7: UUID="XXXX-XXXX" TYPE="ext4" 
/dev/sda8: UUID="XXXX-XXXX" TYPE="ext4" 
/dev/sdb1: LABEL="p" UUID="XXXX-XXXX" TYPE="vfat"

get your device path and fire mount command for usb-stick.

Solution 3:

Device names of flash drives

A flash drive can be connected

via USB (typically a USB stick or a memory card via a USB adapter)
the device name is the same as for SATA drives, /dev/sdx
and partitions are named /dev/sdxn

where x is the device letter and n the partition number, for example /dev/sda1

via PCI (typically a memory card in a built-in slot in a laptop)
the device name is /dev/mmcblkm
and partitions are named /dev/mmcblkmpn

where m is the device number and n the partition number, for example /dev/mmcblk0p1

Example with an SSD, HDD, USB pendrive and an SD card

Edit for lsblk list: With modern versions of Ubuntu you need not use sudo, and when there are (many) snaps, and we don't want them to clutter the list, you the following command line,

lsblk -o model,name,fstype,size,label,mountpoint | grep -v " loop.*snap"

parted
