@impeham:

usbmode has nothing to do with usb disk... usbmode is just application which switch between usb modes (peripheral & host) and is independent of attached usb device (mouse, keyboard, usb disk...).

what mouting usb disk is ke-recv daemon. source code is on gitorious: https://gitorious.org/community-ssu/ke-recv

so if you want to support ntfs-3g you need to add it into ke-recv
