Define the callback

{
@Override
public void onSCSIOperationCompleted(int status, int dataResidue)
{
// status 0: completed successfully
// status 1: Some error occurred
}
@Override

{
// Data received in the data-phase.
// Possible responses: SCSIInquiryResponse, SCSIModeSense10Response, SCSIRead10Response,
// SCSIReadCapacity10, SCSIReportLuns, SCSIRequestSense
}
@Override
public void onSCSIOperationStarted(boolean status)
{
// SCSI operation started

Create the SCSICommunicator object
SCSICommunicator comm;
comm = new SCSICommunicator(mDevice, mConnection);
comm.openSCSICommunicator(scsiInterface);
//..

comm.closeSCSICommunicator();
