Read a NTFS disk in read+write mode

Installing and Using OpenWrt
#1

Wiki says that mount command allows to mount a NTFS disk/partition in read only mode, and that ntfs-3g command is needed to mount it in read/write mode.

Moreover, it says that:

For OpenWrt to be able to mount it automatically:
ln -s /usr/bin/ntfs-3g /sbin/mount.ntfs

Well, I built such symbolic link.

Indeed, when I mount my NTFS disk by mount command using the shell, I can access it in read/write mode.
But when I mount it by the Mount attached devices button in System > Mount Points, it is mounted in read only mode.

Why?

Here below the screenshot showing how the disk appears in my mount points list.

Same mount point permissions on both occasions?

#3

What does you mean with "mount point permissions"?

In System > Mount Points, I've set up rw as option. When I mount using the shell, I specify -o -rw.

#4

the directory used for mounting, what permissions does it have ?

# ls -ld /mnt/usb3
