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
