Subject: [directmusic] can't list my device

the device is a usb midi keyboard. it's not listed in the directmusic
(directx caps viewer) but it is in the windows control panel sounds and
multimedia. i can play through it with the media player (and other
applications) and it works.
why direct music can't open it? is there anything I can do to use it
with my
direct music application?
