Try running

sudo blkid

on the command line while more than one being plugged in. The partition/volume should have a unique identifier.

Alternatively, you could also use the device serial, if provided by the manufacturer.

Run lsusb -vvv and identify the device, then look for the iSerial field, e.g.:

Bus 004 Device 005: ID 059f:1049 LaCie, Ltd rikiki Harddrive

Device Descriptor:

  bLength                18

  [...]

  iManufacturer           2 LaCie

  iProduct                3 Rikiki USB 3

  iSerial                 1 00000000d49425f030b6
