If you want to access a usb storage device, or any other storage, first you need to mount this device to your filesystem.
You need to know the name of the device. If you do not know how to do that, read this post.
Then you need to create a mount point.
sudo mkdir /media/usbNew
Now you can mount the device to the mount point you created before
sudo mount /dev/sda1 /media/usbNew
More information about mount here.
Now if you want to unmount this device, you must use umount command
sudo umount /media/usbNew
