USB MIDI question...

Hi there...

I am just starting to port my OS9 usb midi driver to X. I have a couple
questions...thanks in advance...

1. On OS9 I have an OMS driver *and* a usb driver. I think that on X I only need
a single binary which is a plug-in to the midi server. Does this sound right?

2. My device is based on the EZ-USB chip and needs a "download driver" as well
as the actual midi driver. On OS9 these were separate usb drivers. On X I am not
sure exactly how this works. Do I need 2 separate usb drivers like on OS9? Or
can I incorporate the download functionality into the midi driver itself?

3. With OMS, I know exactly how and when it scans for new midi devices. On X,
when does the midi server re-scan the bus? Or, maybe it deosn't scan, it waits
for notifications instead?

Thanks for your help!
-Ted
