I distinctly remember that there was a simple command to "re-insert" a USB stick after you've removed/ejected it in Nautilus or Nemo by clicking the little eject icon or unmounting it. The command:
does not work. It was a simple command or sets of commands. Not some sort of script. Does anybody know how to re-insert an USB stich wirthout physically removing and re-inserting it?

Try partprobe.

Thanks for the tip! I'm afraid that's not it, or it doesn't work anymore in Linux Mint 17.1 (yes I know: I really should upgrade! )

hmm..not possible to logout or reboot to see if it will help?

or check out this link you might get some idea: https://unix.stackexchange.com/quest...ted-usb-device

Maybe use umount instead of eject, then try partprobe. That's the method I use in KDE.

Try

Thanks all for the tips again. The command above does the same thing as clicking on the little eject icon in my file manager Nemo (or running sudo eject /dev/sdc). The light on my USB stick goes off and it disappears from the list of devices in Nemo. After that command it also doesn't show up anymore in the command lsblk. When I use any command with umount in it the light stays on and it's easy peasy to remount it.

Maybe I'm wrong: after ejecting and/or power-off it's not possible to get power on without re-inserting the USB stick.

When I format an USB stick I always remove and re-insert the stick to force Linux to re-read the new partition table etc. I thought I remembered that I issued a command that would do the same thing without touching the USB stick. Guess I'm wrong...
