    huh...
    I type this into Google...
    jdm programmer usb
    and on the first hit, I get a standard jdm programmer circuit with a serial port at one end.
    I type in usb converter, and I get lots of hits for a USB-serial converter...and get this...I also get hits for USB-serial adapter chips...like one from FTDI, a CP2102, a CP2103...
    Amazing isn't it...!!!
    That Google is one neato search engine ain't it?

    The JDM, while easy to make is very iffy in the best of circumstances (with a proper serial port). With a USB-to-serial converter, it will NOT work.

    If you insist on building your own programmer, google for PICKit2 clones.

    If you work really fast, or your time is not to valuable, then build one.
    Or save the headache and buy a PICKIT2 from microchip. Plugs into the USB port.
