    Hi,
    I am wandering if it is possible to convert stereo audio component output to USB. I am new to this, but I am willing to learn, I found out that Pin 1 of USB connector is 5 Volt DC Power, Pin 2 is Data -, Pin 3 is Data +, Pin 4 is Ground. I appreciate any help :)

    Your component stereo from the RCA plugs (phono plugs) are analog signals, and USB only transfers digital.

    That means that between the analog output and the USB cable there will have to be an analog to digital converter, plus a means of storing the converter output until the entire song/audio signal has finished, so the digitized values can be turned into a WAV or MP3 file. The entire file would be the thing transfered through the USB port.

    Things you can look into:

    1. Stereo analog to digital converter

    2. Using your computer's sound card to make WAV or MP3 files

    or you would stream your digitized audio through isochronous endpoints.
