Here are the commands to use fast the USB stick on a Linux system:

1. Insert the USB stick
2. dmesg = The system displays a series of log where the end is the name of the position assigned to the USB device (example: "sdb1")
3. mkdir nomeCartellaTemp = Create a folder that points to the resource USB
4. mount /dev/sdb1/ user/NomeCartellaTemp = point the folder you created in the preceding paragraph to the name of the USB resource identified in step 2, then use this temporary folder like your key.
5. umount /user/NomeCartellaTemp = when you have finished working with the USB stick you can execute this command to disconnect the pointing. Warning before running the command position yourself on a different folder otherwise you receive the following error message "device is busy".
