yes, you can, but it takes some work and API knowladge... there is a book
out there on this topic, I can't remember the name, maybe someone else here
knows it about communicating with USB ports though the Win API

Hi,

You normally use whatever API is required for the specific hardware device
that is attached to the USB port. There is no general-purpose driver for
this. So, if you are connecting to a serial device, you use the Windows
serial APIs. If a sound device, you use the MCI APIs. If a disk drive, you
use the various file APIs. The actual driver that is installed when Windows
detects the USB device translates these Windows APIs to the device specific
commands required for the actual hardware.

However, if you have custom built USB hardware, you need lower level access
to the device. You must know A LOT about the hardware before this sort of
thing is useful. I suggest that you get a copy of Jan Axelson's book, USB
Complete, 2nd Edition. You can get information on it from the Books link on
my homepage.
