Do you have any simplest code and "exact" steps to reproduce the issue. |

Nop, it happens occasionally in the ESP-IDF implementation and when it happens is a backtrace impossible due to muktitasking. It must be that tinyUSB keeps thinking that the transmit buffer is not sent and sends it again. I was hoping that here somebody knows tinyUSB to point me to the source where (as CDC device) the data buffer is handled. I think that a byte buffer goes out of bound and overwrites e.g. the flag marking the buffer as sent. |

I will move this to discussion, since there is no way to fix a bug without an way to reproduce it reliably. Also IDF also add its own integration/management code on top of tinyusb, you may need to also look at those as well. cdc_device.c is available at src/class/cdc you could check that out. |

What happened ?
occasionally messages sent are repeated infinitive . sending a new message stops this or get repeated infinitive as well.
How to reproduce ?
required a bigger application making use of stack and heap more exessive
