#9841 has broken ESP32-S2 and ESP32-S3 USB

PR #9841 (ESP32-P4 USB support) caused USB to stop working on ESP32-S2 and ESP32-S3 builds. The boards no longer appear on USB. CircuitPython is still working: a blink program still blinks.

I did a bisect to reduce the problem to #9841.

On other ports, like nordic and atmel-samd, USB still works.
