How can I tell which device the USB drive is assigned as?

Before inserting the USB drive:

$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
nvme0n1     259:0    0 238.5G  0 disk 
├─nvme0n1p5 259:3    0  15.9G  0 part [SWAP]
├─nvme0n1p1 259:1    0 222.6G  0 part /
└─nvme0n1p2 259:2    0     1K  0 part

After:

$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    1   1.9G  0 disk 
├─sda2        8:2    1   2.4M  0 part 
└─sda1        8:1    1   1.2G  0 part 
nvme0n1     259:0    0 238.5G  0 disk 
├─nvme0n1p5 259:3    0  15.9G  0 part [SWAP]
├─nvme0n1p1 259:1    0 222.6G  0 part /
└─nvme0n1p2 259:2    0     1K  0 part

Is it /dev/sda??

Best Answer

Simply use lsblk output options to find it out:

lsblk -o NAME,TRAN

which produces:

sda                    sata
├─sda1
└─sda2           
sdb                    usb
└─sdb1                 
sr0                    sata

You can also use other options to get extra information (e.g: SIZE).
If you want a nice clean output use -S:

$ lsblk -So NAME,SIZE,TRAN

NAME   SIZE  TRAN
sda    400G  sata
sdb    16G   usb
sr0    1024M sata
