Unmount an USB sdcard (soft) do no trigger a disconnected event #17

Closed ouaibsky closed 11 months ago

Running on mac (intel 64)
latest lib version: 0.6.1

Event are well received when I plug an sd card.

But when I un-mount (click into the finder on the icon) then no event is received (setOnDeviceDisconnected).

Event (disconnected) is received only when I physically remove the sdcard.

Is it something expected ?

This is to be expected. Unmount is a file system operation. After unmounting the device can no longer be accessed through the file system. But it is still available, e.g. for formatting. And it can be mounted again.

Furthermore for composite devices, unmounting only affects the mass storage part while the other functions (e.g. a serial port) are still in use.
