HID in reports implemented in micropython 1.26 and device.usb are only "arriving" with all bits 0 at the Windows host.

different ESP32S3 boards UM FeatherS3 and plain "vanilla" ESP32S3 Wroom

Firmware

I wrote up a detailed bug report in:

micropython/micropython-lib#1044

But no one seems to care or have simmilar problems.

Using circuitpython I easily can make the USB HID driver work with the same boards!

But for many reasons I want to do this project under micropython.

What happened ?

The driver is "accepted" by Windows
OUT Reports (LED-Values) are correctly arriving "in" the driver.
IN reports are sent correctly, "I think".
My debug code inside the micropython "image/runtime" shows the keyboard values as they should be.
But Wireshark only "sees" keyboard data with "only" zeros!

Any help or comments are very much appreciated!

How to reproduce ?

1. load boot.py and main.py and the device.usb libs to a ESP32S3 board running micropython.
2. Watch the traffic (sending NUM_LOCK keys) to windows.
3. Press NUM_LOCK or CAPS_LOCK on the Windows keyboard and see the correct debug code for LED Values
