Code should work on L151C8 without any modifications.\r\nThis USB example had been taken from the SPL library and its have one significant imperfection - with enabled code optimization (-O1, -O2, etc.) the MCU will stuck in the USB IRQ handler. If you compiled this code with optimization, try to disable it. If not - there is next question: what means \"virtual com port doesn't shown up\"? The USB device appears in system, but not recognized or system doesn't see device at all?\r\nPS: code, ported from the CubeMX, works with optimizations enabled. But still lack any functionality except a simple loobpack."}}
