Usb Flash Drive As Memory Unit
Posted 24 November 2005 - 04:12 AM
What I want to know is: has anyone made any progress on using a regular USB flash drive as a memory unit? Is the difference between it and a memory unit in the hardware or is it formatted specially? I realize nobody has probably done this yet, but hopefully this can spark some interest. Thanks.

My main problem is that none of the stores have harddrives.
I dont wan't to buy a mem card roughly half the price of the hard drive

USB devices have certain identifiers such as serial number, product name, and manufacturer that are known to the kernel but not prominently displayed to the user. On linux with udev, you can get insane amounts of info on the device. The problem is causing an existing mass storage device to report what we want.
I'm interested to see the output of the following command:
udevinfo -a -p `udevinfo -q path -n /dev/<the memory card device (not partition)>`

Hopefully, the only thing keeping the 360 from recognizing a memory stick as a Memory Unit is the port you plug it into, and all you need is an adaptor. But this is doubtful.
Can anyone confirm that there's +5V going from pin 1 to 5? I can't find my tools at the moment.
...hmm. I wonder if MS did anything to prevent reading a memory unit on a computer? Other than encryption or a funky filesystem, I mean.

Pin 1 = 0
Pin 2 = 0
Pin 3 = 0
Pin 4 = 3.27 volts
Pin 5 = 0
So there we have it... might be able to somehow figure out how to run a card reader off of it if we can figure out the data pin configuration, but I'm not sure if a normal USB memstick will run off of only 3.3v.
Ok, after another quick test, I've discovered the outer pins are both grounds.
So theoretically the layout is probabley
Pin 1 = Ground
Pin 2 = Data
Pin 3 = Data
Pin 4 = Power
Pin 5 = Ground
The extra yellow wire from the original xbox controller isn't needed because we're only powering a memcard, not an entire controller????
Anyone know how to decipher which data pin goes to plus or minus? Trial and error I guess If its layed out like a normal port then it should be that pin 3 is - and pin 2 is +
Might try wiring some stuff up to the port and see what happens when I plug in a memstick
oh and heres the link to another thread I started before this one evolved to memcard slots

So may not have enough power to run a memstick if this is the case... may try it later with my xD to usb converter as well... if anyone has an OPEN console, you might try soldering directly to the board instead... maybe MS deliberately lowered the power for the port so that USB devices aren't compliant. If we could bypass this limit, maybe we could get it to recognize... i might try pulling 5v from the front USB ports later, but right now I've got homework to do
Good luck all
EDIT: Ok, only took about 5 seconds... tried it with power off of USB ports and still nothing... got the memstick to power up though (LED blinked)... so it might be that I'm not getting a good connection with the data pins, but I'm really not willing to crack the case on my box to figure it out
