    How do I create a pipe line & upload the data within the FLASH of AT91SAM7X512?

    I just want to copy the data that's in the FLASH and paste it to some file as plain text.
    Later I'll modify the data (which is in the file) to whatever I need.

    Despite the micro-controller implementation of the USB interface, it's extremely difficult to understand how should I do that from the obscure information that's supplied in the data sheets.

    Please help me to understand the process of USB communication initialization & data transferring.
    I've read about the USB protocol & think that I know it well enough.

    For now, when I connect the micro-controller development Kit to my PC via USB, Windows XP does NOT recognize my device.

    Thanks in advance.

    Best regards,
