What happened ?
When sending CDC packets from the ESP32-S3 host, random packets which are 174 bytes in length stall on the last packet which is less than 64 bytes. This causes the driver/process to hang, and no further data is sent.
Several transfers are completed successfully, but then seemingly random after 5-10 174 byte transfers, the 3rd packet which is only 46 bytes long is not transmitted, but the Adafruit API returns the correct number of sent bytes.
This is confirmed by monitoring USB traffic with an analyser.
How to reproduce ?
