Hi, Everyone!
I'm working on project ie usb otg communication with STM32F At first, usb virtual com port driver (COM4) was detected in Device Manager. But after I enter the program, the usb virtual com port driver is suddenly not detected at all in Device Manager. To be detected again, I tried to remove the program on STM32F070 board using STM-ST LINK Utility. However the usb virtual com port driver was still undetectable anymore. Is there any suggestion from all of you, what shoud I do? As an illustration, I'm attaching some pictures related
to the project I'm working on.
