I'm working on a STM32L1 board using CDC but there is problem i'm facing to communicate, the problem is my PC does not detect the USB Virtual COM port,
> All the necessary drivers has been installed properly.
> Stack size is 0x2000
> Heap size is 0x4000
(These two values taken from the sources for solution)
> External crystal has been connected.
is there anything that i'm missed something here or have any idea to solve this problem?
