[SOLVED] PCAN QList Error when using a USB hub
-
Hello,
I'm using PCAN to generate and send CAN Messages. Everything worked till now, I could create and send Messages. And I could see all my send CAN Messages on the PCAN-View Tool.
My problem now is that I pluged in a USB hub where I have two serial devices pluged in.
Now I get: ASSERT failure in QList<T>::at: "index out of range" when I call a PCAN libary function.QPair<bool, BYTE> Simulation::checkUSBChannel() { int iBuffer; TPCANStatus state; for(BYTE i = 0; i < 8; i++) { state = CANDriver->GetValue(handleArr[i], //when I call this function I get the error PCAN_CHANNEL_CONDITION, (void*)&iBuffer, sizeof(iBuffer)); if((state == PCAN_ERROR_OK) && (iBuffer == PCAN_CHANNEL_AVAILABLE)) return QPair<bool, BYTE>(true, handleArr[i]); } return QPair<bool, int>(false, 0); } TPCANStatus PCANBasicClass::GetValue( BYTE Channel, BYTE Parameter, void *Buffer, DWORD BufferLength) { if(!functionLoaded) //the function gets loaded from the dll file return PCAN_ERROR_UNKNOWN; //and when i call this the QList error occures return (TPCANStatus)m_pGetValue(Channel, Parameter, Buffer, BufferLength); }
I also get this error when I call the PCAN initialize function.
When I only plug in the PCAN USBstick into the hub it works too, but as soon as I plug in one of my serial devices anywhere on my PC I get that error again. The PCAN Applications are working no mather what I plug in and where.I have absolutly no clue what is wrong.
If some one has any idea what could be wrong, please answer.
Thanks to everyone -
I think I solved it. I pluged the electricity source into the USB hub and now it is working (still don't really know why). I will do some more testing, if it still works I will change the topic to [soved].
