I was playing around with my USB GPS receiver the other day and started to wonder how hard it would be to integrate it into my applications (more on this in the future). The first challenge I had was to be able to talk with it via the USB port and gather the location data.
It was a late at night and my mind was not functioning at 100%, or even 25%. So I want out to
It was only after a few minutes that my brain caught up and it hit me that the S in USB was for serial. A simple fact and the fact that it took me a matter of minutes to wake up to this should have caused me to head to bed and get some sleep but no such luck.
Moral of my story, if you are looking at talking with either a Serial port or a USB device you can access it with some of the code from this sample.
It is an older sample but works great. Saves you the pain of having to interact with or wrap the Win32 APIs for serial access yourself.
