Hi Pavel A,Thanks for your response, i am looking for USB Device CCID class specifically.

Hi i am trying to start a project but in the CubeMx while initializing connectivity and USB device middleware i can not see other types billboard and etc, could please help me to sort out this problem, Thanks

 while (HAL_OK != ATR_Read(&SCInterface, atr_buff, &atr_size));this is the line where code stucks

Hi Imen,I followed the guide you provided and now i have uploaded the code to mcu, but it is not reading any data from Smart card. where you think error could be.Thanks

and i don't want to use the library are there any commands like for HAL_uart, for smart card in cube ide when we initialize any usart as smart card with clock so i can use those and communicate with card. Thanks
