the USB exploit we are using with PSJailbreak/PSGroove/PSFreedom/Whateverelse tickles your fancy.. use any files...
instead of emulates a 6 port USB hub, and cycles through each of them emulating them being plugged in and out in a certain timing and sequence... among this is rather large descriptors (think of when you plug a USB something into your PC it comes up what is it like USB Camera etc) that make the ps3 do what its not supposed to... there will never be any way to hack the ps3 using the same exploit by just adding files to a usb storage device... its just not going to happen.
Like Plexo says, the usb device is more than a simple memory card and controller, it needs to have some sort of processing power in order to emulate a usb hub plus the software contained on virtual usb devices that are quickly inserted and removed in a specific sequence and timing is also crucial.
So this will NEVER appear on a simple usb memory stick, it might look like one form the outside, but on the inside there is some sort of microcontroller pumping away doing all the work.
The hacks real when using a real jailbreak device obviously, but this video is a fake. Its a parody of the orignal video released by oz mods. There trying to make users believe you can turn a normal pen drive into a jailbreak device. Hence why your asked to fill in the survey to download the file in the link. God knows what the file contains but im not willing to fill in the survey to find out
