What happened ?

On pico rp2040 host, control endpoint get blocked after a random period of time. The status stage is missing and no more control_xfer is possible.

On a specific roline mouse, enumeration fails with wrong data toggle from the device. The USB_INTS_ERROR_DATA_SEQ_BITS is not handled in the current version of the sdk. The driver just panics.

How to reproduce ?

Compile the attached modified firmware and connect a keyboad. The scrolllock and capslock LED will blink (250ms). After a random period of time the blinking stops and the control endpoint is blocked.
For the data toggling issue, connect a roline mouse and enumeration will fail.

I have checked existing issues, dicussion and documentation

@kilograham this might be an issue with the rp2040 usb host controller. TinyUSB host does not handle the wrong data toggle error but when I connect the same device to other host controllers including Windows, I don't get such an error.
