I've received and tried that connector, and you know what? It doesn't work! dmesg shows nothing happened when I plugged any usb devices (mouse, keyboard, flashdisk, 3g modem). Means usb host does not have physical connection into this 30 pin port.Well, at least I've tried that so I won't spend the rest of my life wondering this.Just tried that connector on my friend's flytouch thing, and it works. Dmesg reports usb devices I plugged in. So, I gave it to him.
