I have an USB Dongle that I'd like to put inside my Macbook Pro. I have already found a spot that will fit the dongle. The next question is splicing one of the USB ports and connecting it to the dongle.

Here's a photograph of the inside of my Macbook Pro, showing the USB ports and a little gray plastic divider with four holes in it above each port.

enter image description here

My question:

Does anyone know what is inside these holes? Presumably each one is a pin for the USB port, right? Can I just stick a wire in there, giving me 4 pins, plus the fifth attached to the metal outside the port?

More generally, any one have any ideas for what might be the easiest way to get a USB port inside my MBP? :)

Just behind the connector indicated there are 4 small solder pads - 3 round and 1 square - these are the same on all the USB ports and I believe this is where the port is connected to the motherboard.

If you're very very very very good with a soldering iron you would be best off soldering 4 fine wires to these points and routing them to your internal USB device.

Note that the socket will become unusable, so blocking it off would be good - or even better, removing it altogether. This would make soldering the wires in easier.

Not an easy job to do and the slightest slip could kill your MBP.

Great, thank you. Question - why would the socket become unusable? Would it be possible to put a "hub" in there somehow so that everything still worked? – MikeC8 Feb 27 '11 at 2:15
To do that you would have to disconnect the socket from the motherboard and connect it directly to the hub. You can only connect one device at a time to a USB port, so any wires connected to the USB port on the inside would constitute that port's device. – Majenko Feb 27 '11 at 9:34

Looks like it's been a while since anyone's added to this. I've been recently looking to add internal USBs as well and thought I am looking for the Macbook (not Pro) I assume there are some similarities. Among this website, I also stumbled upon another that gave more details about this port you are describing. In it they say the rear USB port (closest to the screen) already has a USB hub connected to it powering the IR, camera, trackpad, and keyboard.

Knowing this, I would take away two things; 1. don't bog down that port with more stuff, and 2. the other ports MAY have the capability of running a hub. Here's the site that I learned this from:
