Usb Flash Drive As Memory Unit, Any progress? Options

[leorimolo]

I know it aint gona work but why not try to load the splinter cell exploit, well I mean the 360 is fully emulating the xbox

LEo-I know it wont work but id be cool

JoHnnyTK36 awesome work on your word tutorial very well done!!!!
maximilian0017 amazing work on the drivers!!!

Maybe post that tut in a new thread so the XSMODS can sticky it and post the drivers/tutorial on in the news

Luckely MS has a standard USB Storage driver, the problem is that it didn't detect the new class used for the X360 Memory Unit.
After modifying the INF file and stripping the unneeded stuff that would accept the new memory unit.

Then i modyfied the INF file for volume management and stripped it

The most difficult one was to make an inf file for the other device i called security device, that one needed a dummy driver so that it would show up under USB devices

Hopefully this will make it a little bit easyer

What's next?

Thats a good idea, the more people who know about it the faster it gets blown open.

I'm in contact with JoHnnyTK36 about both our guides, maby we can find something in the middle that offers all the benefits(easy/safe/cheap/no restrictions)

Any word on that linux live cd with xtaf support?

Hmm, this is getting interesting. Have any of you tried to dd a dump of a MU to a USB memory device and connecting it to a 360? It'd need external power of course, IIRC the MUs run on 3,3v was it? So you'd need to get 5v from some other place, like a USB connector on the 360.

I'd try it without 5v first, wouldn't be amazed if it would work because of the kind of electronics used, and it's less dangerous


But why would you use a memorystick if you already have a x360 memoryunt (besides from it being very small)

[JoHnnyTK36]

i have already tried that. it did not work, atleast with the flashdrive i have. I tried it using the supplied 3.3 volts and 5volts.

It's probably due to the other 3 virtual usb devices(yes 3 others) located on the Memory Unit, or even a checksum/code of sorts(see the bigger harddisk topic), did the xbox "look" for someting?(lock for a short amount of time after you connected the memory stick?)

Kezor:
(No offense ofcourse)
It takes about the same time to make as both the other guides, but they dont have wires that can come loose.
Test/bread-boards have the tendancy to blow up in your face, they are meant to test idea's/proof of concept, a wire that comes loose a little bit/connected wrong and byebye Xbox, you have to check everything before you connect it again.
If you want to try it 1 time it's a good idea, but as you already need to strip and solder once you can solder the rest too and have a permanent sollution.

Why did you use 2x30 ohms for the Vusb?, Johnny already stated that 20ohms total would be enough.

Both of the datalines use 5v, they should have 33 Ohms or so resistors too(see post 123)

You can loose the ground wire, not needed(i have a 1 meter usb cord permanently attached, no extra connectors/wires needed, can copy images from the xbox, unplug, go to pc and plug the usb plug in)

Just for the fun of it ^^
Nah, maybe this could lead us somewhere inside the xbox, making custom gamer pics (except MS would ban us all ) etc.

But for the Xbox to recgonize our memory sticks we'd need to somehow emulate those other USB devices, like that "Xbox Security Method" etc. Maybe we could wire the MU and the usb storage device to a switch, then connect the MU to the Xbox, let it authenticate it and the flip the switch so the 360 sees the USB storage device instead. Good thing that MS uses standards ^^

Would it be possible to isolate the security device on a MU and make a pass through device for a normal USB Flash? I was wondering the same thing about the security device on controllers, but that's kinda unrelated.

[loser]

just wanted to add my 2 cents into the mix

firstly i'd suggest going maximillian's route, but if you cant source an LM1084, you can use an LM317 with R1=240ohms, R2=390ohms. i did this and it works fine in both the xbox and pc without having to remove any cables.

secondly ive updated maximillians drivers to give winxp x64 support, you can get them here:
http://www.internalreality.com/X360MemoryUnitDriversV1.2.rar

does anyone know if there are any existing windows tools to give filesystem access to the memcard?

[maximilian0017]

Yesssss, we made it to the news on xbox-scene.com, hopefully this will bring in some new blood!!!

On free60 there are people believing that the chip on the MU is a programnable chip from Philips, maby someone with an USB analizer and knowledge of small programmable microcontrollers could do something.

If you want more storage the easyer way would be to place a secondary 64mb chip on the backside of the MU, making it a 128MB device.
This way you could also see if there are safeguards like on the the hd.

Loser:
U R right, the voltage regulator is the best option but not all people have an understanding of electronics, the 317 is a very nice alternative(easy to get), but there are two other resistors to connect making it more difficult for the non electronics guys, if we were to be completely correct we would also need a capacitor.

Far out the easyest would be leaving out the voltage regulator and replacing it with a resistor of 18-22 Ohms and putting two resistors of 33 Ohms in the two datalines, this way the mod would be alot easyer and faster.
(been discussing this with JohnnyTK36 for a while)

And great work on the x64 drivers, together we stand strong!!

I tried all of the tools used for the old XB and they dont work(even after a little modding) if those people would help they could release the sourcecode or modiy it for the MU we would be in business(if it werent for those strange packages used )

First there is a tool in the works to allow you to access the memory via windows. Stayed tunned, it should be out not vey long from now.

I have already tried putting another card on the back of the memory card. So far it didnt work, but i think some of my solder joints weren't that good. I need to try and do some more experiments with it.

[Bumpy Carrot]

So has anyone confirmed that the 360 MU uses the big-endian FATX FS yet? Also, did anyone ever figure out the FS for the original XB memory units? I have a pendrive I use as my MU for the original XB, and I thought it might be cool if I could rip my original XB saves off it and dump it to the 360's MU or HDD. I'm not quite ready to mod my original XB yet (and, also, my brother borrowed it).

[Angerwound]

The tool Johnny speaks of is Xplorer 360. It will be a filesystem explorer that will allow you to extract/delete/add profiles and saves to the memory unit itself. See www.360GameSaves.com for more info.
