This works as intended with CircuitPython 9.2.9, so this is broken as of version 10.

I think the S3 at least has some web workflow issues. On the ESP32 it's been very snappy for me.

Ok, cool. I'm just using 9.2.9 for now.

Running into this issue as well.

When using a Lilygo T Dongle S3 plugged into a USB power brick, I'm receiving a USB storage active. message when trying to create a folder named 'test' on the drive.

Looking through the code it looks like the file system is locked here and bubbles up as a FR_WRITE_PROTECTED error.

Since https://forums.adafruit.com/viewtopic.php?p=1078149 is locked, I'm replying (much delayed) here. I have a bunch of Seeedstudio ESP32-C3 exhibiting the web workflow failures, but have also seen this on an Adafruit Feather (forget which one) in teaching CPy.
