I want to use my ESP32-S3 as a USB MSC device. Instead of proxying filesystem calls to the SPI flash or SDMMC, I want to intercept them and fetch the information from a remote server. Is it possible to do this with ESP-IDF?

Help is appreciated.

In theory it should be possible, but may be very very slow.
