Issue with the customized board is that, it does not detects USB(FS CDC) comport every time as we plug/unplug the device.
whereas the same firmware works fine with ST nucleo board of STM32F070RBTx.
1. Do programmer needs to add any additional delay for external crystal stabilization?
2. Do STM32 cubeMx generated firmware take cares of that power on delay?
3. Can CSS block help in detecting external clock issue and how?
