unsafe_disable_usb_drive() cannot be undone

[bablokb]

CircuitPython version and board name

Adafruit CircuitPython 10.3.1 on 2026-09-14; Raspberry Pi Pico with rp2040

Code/REPL

>>> import storage
>>> storage.unsafe_disable_usb_drive()
>>> storage.remount("/", readonly=True, disable_concurrent_write_protection=True)
Zurückverfolgung (jüngste Aufforderung zuletzt):
  Datei "<stdin>", Zeile 1, in <module>
RuntimeError: Der Pfad kann nicht neu gemountet werden, wenn er über USB sichtbar ist.

Behavior

I fail to enable the usb-drive again in normal read-write mode for the host. After disabling the drive, I can re-enable it with storage.enable_usb_drive(), but it is read-only for the host. The docs say:

If you call enable_usb_drive() after code.py starts or in the REPL, you can reverse the effect of a previous unsafe_disable_usb_drive(). The CIRCUITPY drive will reappear to the host, and become read-only again if it was previously read-only.

Before storage.unsafe_disable_usb_drive() it was read-write for the host, so I expect it to be read-write again?!

The RunTime error above is also an error: after storage.unsafe_disable_usb_drive() the drive is not visible via USB, so no need to bail out.

Description

No response

Detected with 10.3.0 already, but nothing changed with 10.3.1.
