Thanks PS-PabloGS. We had the same problem but on the L151. If it helps anyone else, on the STM32L151 if using an external oscillator (HSE in bypass mode) the bootloader doesn't seem to handle this so you need a pulldown resistor (1k?) or pulldown ca...
Thanks very much for the link! I don't have the faulty device anymore to investigate further, but most likely that was the cause for us too, as we were using custom OB, and setting RDP within the app etc... So looks like maybe there's a glitch somewh...

Hi, did you ever find a solution to this? I have the exact same problem (STM32L4).If the computer closes the VCP, when it re-opens, it receives the last packet that the STM32 tried to previously transmit. I want to know how to clear the USB TX buffer...
