Presumably given as root.

Type:
$ ls -l /dev/disk/by-label/
to see what the kernel called your stick. Debian installers have LABELs.

There's a # before that line

That line looks spurious. If you put it there, I would remove it for
the time being. When you mount a USB stick as root, you don't need
an entry in fstab, but you do need to create a mount point first.
Of course, this has been done for you as a convenience: there is
a /mnt directory specifically for temporarily mounting a device.

Cheers,
David.
