I want to have USB-NCM Together with Littlefs.

this combination I feel is not healthy.
it seems the USB Package draws fatfs Package and makes weird things.

System stable again after i completely removed USB.

i would like to re-add USB, if it does not affect System stability, but currently i fear, littleFS is not working togeter with USB-NCM due to less testing and debugging at Espressif side.

maybe some dependencies need a #ifdef to not use fatfs components, especially in that case that i am only interested in NCM.

currently this is unstable in my Observation.

the second case should run as well: FATFS on a USB Stick, but littlefs on internal flash, should not be a Problem in future.

@diplfranzhoepfinger Please provide more information about your issue. Eg. logs, reproducible code, configuration etc

This is not enough information for us to start debugging
