I also have the same problem.

I create usb cdc project by cubeMx on stm32l152,

The usb can enumeration success, I can find the com port on my pc.

I also can receive one byte from pc by hypertrm, but the program will always into HAL_PCD_IRQHandler, because the USB_ISTR_SOF flag always set.

Is the behavior normally?

Is there has simple echo example code that workable for usb cdc?

Thank you stm sirs!
