    You need USB and that has to be the more complex USB host. USB host (OTG) is available in some PIC32MX microcontrollers.

    It isn't going to be a walk in the park.
    If I understand right you need a PIC which can be a USB host, it's possible you might need (or it would be easier) with 2 of them.
    If you go here and click USB, then look in the USB column for OTG I think they are the ones you need. I think the ones that have device in the column can only be USB slaves so couldn't interface with the pendrive. There's a lot of documentation to read though on the site.
    (This is about the limit of my knowledge, I've never done any of this).

    You could use a SD card, as a workaround. That will be much simpler. And a lot of samples out on the net

    I can't believe you bunch falling for OP to make him a pen drive duplicator.

    Are guys wiling to practically handed over a USB memory stick copier on the go to some Indian who may or may not be in the businesses of selling these kinda stuff, or OP may or may not try to steal unsuspecting individuals data with in a second or so.

    Think about it.
