I use STM32MxCube to install example code. I selected STM32H7 to finde the Nx_Iperf example for the STM32H747I-DISCO board. When I select Start Project, the progress bar runs to completion then I get a message "FAILED TO INSTALL EXAMPLE: Nx_Iperf"....

In CDC_Control_HS(uint8_t cmd, uint8_t* pbuf, uint16_t length), when cmd is CDC_SET_CONTROL_LINE_STATE, length is 0. It seems like it should be sizeof(USBD_SetupReqTypedef) = 8.

I found this link:https://community.st.com/s/question/0D50X00009XkfHnSAJ/usb-vcp-how-to-know-if-host-com-port-is-openwhich uses CDC_SET_CONTROL_LINE_STATE to set and clear a flag. It reads data in pbuf even though length is 0.Is this a bug in the co...

Thank you for your answer. I will try testing DTR. Also it sounds like you suggest using a timeout when sending data.I send data this way: while(CDC_Transmit_HS(array, size) == USBD_BUSY) ;but I only want to do this if there is a connect...

Sorry, I do not understand what code changes you are suggesting. Also, I need to detect the case where the host has opened the device, even if there is no data being transferred. When I open a terminal program on the host I am able to send and rece...
