Locating & Identifying propeller chip via USB

Hello All,

I'm rather new here & hope some kind soul could direct me to a link or note to read up on how an app (Java or any desktop app) could locate, identify & connect to a propeller-chip board if it is connected via the USB. I'll be using SPIN on the propeller and I think I'll need to allocate Pin 30 & 31 for polling but how do I use, say Javax.comm, to connect to propeller?

Thanks in advance.

    I think the Propellant library can do that... I believe there's a dll interface for it.

    Hi,
    The standard javax.comm library originally developed for linux but extended for win32 works fine for me, no resets. The library will not work on a 64 bit JVM but I am able to control multiple quickstart boards simultaneously from a single java process after first reloading them all using propellent in an Ant script.

    see http://javahardware.blogspot.com/2010/11/led-display-board-driven-by-javaxcomm.html

    @Michael,

    This is cool! Its funny, when you needed something its always hard to find but they seems to jump right in front of you when you don't. -_-" .... I've actually detoured to VB.net since then but guess its time to re-look at it again (maybe in June).
