XBox 360 Memory Unit USB Connector





Introduction: XBox 360 Memory Unit USB Connector

In this tutorial you will be told how to add a USB connector to your XBox 360's Memory Unit (MU). You should have some experience in soldering and you need some piece of wire, a USB connector of your choice, a 3.3V low drop voltage regulator.

By forcing Windows Vista to use some default drivers, you can access the unit's memory like a USB memory stick. You just need a software tool to read out the XTAF-file system of the unit.

Step 1: Open the Unit

As the manufacturer of your device doesn't want you to open it, the MU is melt/glued so you cannot easily take the case apart. Carefully use a knife/blade or a little screw driver to open the device. Pay attention to the parts inside! They are very sensitive and near the borders of the circuit board.

Step 2: Solder USB Connector to PCB

Now you need your USB connector. Prepare it by stripping the cables inside and cutting off the cable shield. Add solder to the ends of the four wires and cut them a bit so you can precisely solder them to the PCB.

Then connect the black, green and white wire to the pins according to the picture:

The two left leads are shield and ground, the 3rd lead from the left is the +3.3V power pin which will be fed by our voltage regulator from step 3. The next two pins are D- (white) and D+ (green) from USB. The 2nd from the right is GND again (black from USB). The last pin is shield again (as you can see).

Note: Think forward and carefully adjust the cable length to your USB port to fit the case length and inner height! The parts have nearly no space to the top (I needed to modify the case).

Step 3: Add the Voltage Regulator

Now we insert the 3.3V positive voltage regulator. You can get this little thing from your local electronics shop or over the Internet (which might be waste of money as this part shouldn't cost you more than one buck).

It is highly recommended to use a SMD (surface mounted device) part, as there is rarely any space in this freaky small piece of plastic...

Warning! Your part might look exactly the same as mine but you really need to check the pinout using a datasheet you get from your part vendor! The regulator must have a GND or - pin (black in my picture as connected to GND), a Vin or +in pin that goes to the red wire of the USB pin (the 5V from the PC) and a Vout or +out pin that connects to the +3.3V pin of the PCB (blue in my picture).

Note: You do not need to connect the tab of the regulator, it won't warm up seriously and you don't have to glue the part as the case will gently press it down.

Step 4: Close the Case and Enjoy

Now that you have your parts inside, you can put the case back together. You might need to apply some modifications to one or both of the case halfs as you have added the new parts.

I had to remove some area of the bottom half for the connector.

Finally tape the thing so it won't fall into parts again (I used normal transparent tape). You can also glue it but you should take into account that you will void the possibility of servicing the unit again and that you might damage the PCB with the glue.

This tutorial ends here. Have fun and enjoy accessing the holy world of xbox's XTAF file system. I think I will make another instructable about using the unit with a PC (drivers, tools and stuff).

Remember: This will void your guarantee, but it will guarantee you much interesting insight in your game console system and enables you to share savegames and stuff ;)

    I wonder what's this useful for?

    Now that is pretty interesting. I've heard of people doing this before and have always been curious about doing it myself. Looks like I can now.

    Exactly how did you connect the wires to the pins? Did you just put the wire inside the color wire of the usb cord under them?


    can you use this to increase the memory??

    If you don't want to use a regulator, but you feel safe modding your pc, YOu can Make a seperate usb Port that runs 3.3V from the Power supply. a Power supply's Orange wire is 3.3V, you can just splice another wire to one of them for your usb 360 FDD, Don't use a compaq or dell Power suplly sometimes they Make there PSUs proprietery.

    hey i when i compleated the process it worked fine on my pc but when i hooked it up with my console it didnt recognise...........can u tell me wht the problem is

    Possiblie reasons: 1) You disconnected or destroyed some pin of the socket going into the box. 2) You changed something in the MU's file system / raw data any the box invalidates the data as some signatures are wrong or something. 3) The MU Security Method IC got crushed. A PC will still show up the hub and the memory but the box also needs the security method device to check if it is an original unit or just a faked usb device that it would ignore.

    i think i messed up with the file system...........can u help me on this to restore back its original state

    What exactly have you done? Did you try to format the unit with windows (FAT or similar)? Are you sure you have changed somethin? Could it still be the security method chip that is dead-soldered? Is the connector fine? If you are sure its the file system or nothin of the above can solve: Can you format you unit in the xbox (if yes do so) or doesn't it even show up in the System menu?

    Hey i too got it working. Just trying to see how to set up the default USB drivers as you said to make it come up as a drive to be able to use Xplorer360
