Correct. I attempted to build a cable that would trigger dock mode, but was blocked by some Motorola wizardry. My final solution was to use a wire with a heavily trimmed micro USB connector and an NFC tag to trigger dock mode.

I cut the connector down to ~3mm of rubber and superglued it in place.
GeorgeH, did you not have a problem connecting the micro usb through the slot? I printed this out and inserted my cable through the bottom, but the connector is coming out at a different angle (more vertical) than my phone wants to sit. I'm afraid this will ruin the port on my phone if I let it sit like this.

Also, I just used an NFC tag on the middle of the dock to enable dock mode.
Still working to duplicate the Motorola dock cable. I think it has a microprocessor in the cable to perform authentication.

Instructions

Cut down a USB cable so the plug will be long enough to reach through the plastic and make proper contact with the phone's jack. If present, you may file off the little clips that hold the USB connector in place so the phone can be removed easily.

There are cavities to accomidate up to three metal rods for additional weight. Maximum length is 130mm, maximum diameter is 6.35mm. These must be added mid-print.
