Redefining the project Our project, like we think it, can be

named:

“Reverse engineering on the Ipod USB protocol”

Reverse Engineering on the IPod's USB protocol06/11/08

Our Goals Reverse engineer the USB protocol

of the Ipod and understand clearly the way its functions work

Be able to give commands to the Ipod

Understand the answers it gives

Reverse Engineering on the IPod's USB protocol06/11/08

Our Goals Develop an application able to use

directly the discovered protocol

Find a good usage for the protocol

Develop the application itself

USB in a nutshellUSB in a nutshell

Universal Serial Bus (USB) is a serial bus standard to interface devices to a host computer

In response of a data packect, we could have three basic responses : a ACK (data was successfully received) a NAK (data cannot be received at this time) a STALL (device has an error and never transfer

data until some corrective action is perfomed)
