Using Ubuntu desktop is usually mounted automatically, and in command-line mode you need to mount it by command.
1. First look at the information of the U-disk, confirm what partition is displayed, what the USB drive format is.
View command: sudo fdisk-l
2. Mount the U-disk to the specified position.
USB stick format is fat
Command: sudo mount-t vfat/dev/sdc4/home/linux/mnt
Note:/DEV/SDC4 is a USB disk partition display,/HOME/LINUX/MNT is the designated mount location, you can choose. After that, you can see the U-disk information as soon as you enter the folder.
The USB drive format is NTFS
Command: sudo mount-t ntfs-3g/dev/sdc4/home/linux/mnt
3. Unloading the U-disk
Command: sudo umount/home/linux/mnt
Note: You can not mount the folder in the U-disk Uninstall, the equivalent of U-disk in use prohibit exit.
