Description

Adafruit CircuitPython 10.0.0-alpha.7 on 2025-06-17 creates and grants access to the onboard SD card reader on my Metro RP2350.
On a RP2040 it also creates the SD card reader, but it cannot be accessed, configured, or discovered what GPIO pins it is connected to.
If an SD card reader is connected to any of the five SPI ports on a RP2040 W, it does not replace the phantom SD card reader.
It shows up on my Windows 10 machine as an empty SD card reader waiting for a card to be inserted.

Additional information

I believe this feature is very useful for boards that have a built-in and defined SD card reader.
It get in the way and confuses things on boards that do not have a built-in SD card reader.
I at least two cases the phantom SD card reader is created on the Windows drive that appears when the BOOT switch is held down when RESET is pushed.. BOOT/RESET's code gets one Windows drive, while Circuit Python gets another drive during CP operation.
