USB host MSC example fail

[username]

ESP v5.3.1

I created a new project using the example USB/HOST/MSC
https://github.com/espressif/esp-idf/tr ... b/host/msc

When I run it and stick a USB stick in i get the following in the terminal.
Its failing on this line: ESP_ERROR_CHECK(msc_host_vfs_register(msc_device, MNT_PATH, &mount_config, &vfs_handle));

I (371) example: Waiting for USB flash drive to be connected
I (1351) example: MSC device connected

Any thoughts why ?

The error code 0x1701 that you're encountering is ESP_ERR_INVALID_STATE. Looks like the system is not in the correct state to perform the requested operation. Check the mount path (MNT_PATH).

I would think the example should work out of the box though.

Found the cause. USB drive needs to be formatted as FAT. Mine was formatted with exFAT.
Be nice if that was in the README file.
