USB Logger details decription required.



Dear All,
 
Is there any documentation available for details printed out by USB Logger ? I am particularly referring to the terms::
 
IOUSBDeviceUserClient
IOUSBInterfaceUserClient
etc..
 
I am in process of running multiple applications to communicate with my USB bulk device driver and in that process get error while opening the interface, "No such device" 2c0. (plz refer my previous posting " Multiple applications can have access to the > device at a time "for details)Upon looking at the USB Logger I get to see following details  
 "
 IOUSBInterfaceUserClient[0x17afa00]::willTerminate isInactive = 1
  222.147 [3] IOUSBInterfaceUserClient[0x17afa00]::didTerminate isInactive = 1, outstandingIO = 0
 "
What does this mean ? I suppose this is linked with the error I get in my application.
 
Any suggestions / comments in this regard is most welcome.
