I understand the situation & I'm actually one of those :-/ My [last (side) project](https://github.com/rgrr/yapicoprobe) was based on RP2040 and its SDK which uses TinyUSB et al. My current (professional)...

Gosh... the number of screws to turn tends to drive me crazy: on my device, if setting CFG_TUD_NCM_*_NTB_MAX_SIZE=2048 then iperf produces retries. This can be circumvented by setting wNtbOutMaxDatagrams=1, but...

Perhaps a parameter for wNtbOutMaxDatagrams should be added to allow the regular user as well to enter parameter hell!?

fighting with the parameters and trying to understand... that's the current outcome: ```C #ifndef CFG_TUD_NCM_IN_NTB_MAX_SIZE /// must be >> MTU #define CFG_TUD_NCM_IN_NTB_MAX_SIZE (2 * TCP_MSS + 100) // can be...

I have added your suggestions. Currently the NCM driver is not built in the CI. Any idea how to add that?

> I'll do comment and format things :) Also I have to move `#include "lwipopts.h"` to example's `tusb_config.h`, the stack itself should have minimal external dependencies. Thank you very much...

Hello joshikeval3131, to be honest, I'm more or less a novice to (Tiny)USB from developer side. Do you have some pointers where and how to start debugging the NCM code?...

New evidence for the NCM problem. I have done some tests with the iperf server provided in the lwIP examples and recorded with Wireshark. Once I have done the tests...

Hmmm, does anybody read this? I want to make a proposal: the ncm_device driver seems to be very buggy, e.g. it operates on incoming frames while the previous one is...
