Subject: 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?
Yes.
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?
Probably the latter, assuming you can use the USB user client to
implement the download.
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?
In 10.0, it's when the server starts up or someone calls
MIDISetupCreate. We're aware of the desirability of a better
plug-and-play model.
