M-audio Ozone with linux-rt doesnt work!

[Nobre]

I have a M-audio Ozone USB audio and midi interface/controller working great with UbuntuStudio (on Hardy Heron, with the daily latest updates) and 2.6.24-16-generic kernel...
But by default, Ubuntu Studio uses 2.6.24-16-rt (preempt)... I cant get the Ozone (with the madfuload firmware) working with this RT low-latency kernel...

The lsusb shows me the deviced in a bus, connected.
But for some unknow reason, the snd-usb-audio could not get running and just my onboard sound card are founded at "asoundconf list" command.

What should we do?

Thanks, and so sorry... my english is so poor.

I really am convinced about this problem with idvendor and idproduct at powering Ozone and the UDEV.
When the OS identifies as ID 0763:2808 Midiman, I can't get Ozone working.

But if the OS get ID 0763:2008 Midiman... great... it works! so, the madfuload driver could be running only if this ID's is correct!

Im trying to discover how could I test an IF or ELSE code in the/etc/udev/rules.d/42-madfuload.rules file, to load the driver using one of this two IDs...

We no longer have a RT kernel, marking bug as won't fix.
