[QUOTE="raintree_county, post: 773150, member: 114773"] Hi, For TBS5980 USB DVB-S2 CI Box, the USB devices initiation method must be used. On OnInit() function you may find the following method that is used to get m_pKsCtrl variable . //Get the interface //USB Devive init ALL use it 5980 QBOXS QBOXS2 5922 QBOX3 if((DeviceType==3)||(DeviceType==4)||like 5921 QBOXS2 and son) { m_pKsCtrl = NULL; if(!ll_init && m_pTunerDevice != NULL) { hr = m_pTunerDevice->QueryInterface(__uuidof( m_pKsCtrl ), reinterpret_cast< void** >( &m_pKsCtrl ) ); if (FAILED(hr)) { ll_init = 1; MessageBox("m_pTunerDevice QueryInterface Failed","error",MB_OK); m_pKsCtrl = NULL; return FALSE; } } } If by mistake you used the PCI/PCIe devices initiation method, you just can't get DiSEqC work with "QBOX" method. //PCI or PCI-E initDeviceType = 6921,8921,6920,8920, if((DeviceType==1)||(DeviceType==2)||(DeviceType==5)) { m_pKsCtrl = NULL; m_pTunerPin=NULL; m_pTunerPin = FindPinOnFilter(m_pTunerDevice, "Input0"); if(!ll_init && m_pTunerPin != NULL) { hr = m_pTunerPin->QueryInterface(IID_IKsPropertySet, reinterpret_cast<void**>(&m_pKsCtrl)); if (FAILED(hr)) { ll_init = 1; MessageBox("m_pTunerDevice QueryInterface Failed","error",MB_OK); m_pKsCtrl = NULL; return FALSE; } } } Thanks!
