windows wdm midi to usb driver

I am trying to use the FTDI232BM USB to serial chip in a MIDI application.

The FT232BM chip comes with a WDM usb driver and API (FT_Write(lngHandle,

strWriteBuffer, LENGTH_MESSAGE, lngBytesWritten))that I can use to send midi

data to the chip and it will convert to MIDI serial output.  I would like to

use the windows MIDI API functions like IRET =

midiOutShortMsg(MIDI_OUT_HANDLE, MIDIMSG).

My question is what do I have to do to have the FT232BM chip recognized as a

MIDI device?  Why do I want it to be recognized as a MIDI device when I can

already send midi data to it?  So that CAKEWALK and other musical

applications can use it directly.   Any guidance is greatly appreciated.  Thanks in advance.
