time.sleep(5)Behavior
Both CircuitPython 9.2.1 and the current 9.2.4 fail to discover a microSD adapter plugged into the MAX3421E when using a Feather V2. This is using the guide example USB host scan code.
This works with Arduino.
This works with (irq/cs pin changes) using CircuitPython 9.2.4 on a Feather RP2040 DVI.
