heres my start test of CoreAudio in Java. it just don9t work.. I get an
error saying:

DebugAssert: Third Party Client: (*deviceIntf)->USBDeviceOpen(deviceIntf)==
noErr [-536870203] nextDevice [line 123, file USBUtils.cpp]


whats all that about then? I am using a USB midisport2*2 and the driver I
downloaded that works with it. Can see what I am doing wrong in my code. any
pointers would be cool.

Do you get this error if Classic is not running? I suspect you won't.

-536870203 == 0xe00002c5

from IOKit/IOReturn.h:

#define kIOReturnExclusiveAccess iokit_common_err(0x2c5) // exclusive access and
// device already open
