In that case, will you please add "SCSI Pass Through" capability to
libusbx?

Actually my first interest was for some basic USB capabilities like
device discovery.

Sending raw SCSI commands is the conclusion you experts concluded as the
most likely possibility. I had no idea.

I am NOT giving up on libusbx! As a matter of facts, I do need libusbx
for certain functions... I believe it is a great project and it is easy
to use the API, even from Java. I would rather have only ONE library to
deal with, and that is libusbx.
