[question] on unmount callback

[chegewara]

After unplug USB cable from PC i am getting this:

20:34:02.400 -> device unmounted
20:34:02.433 -> device unmounted
20:34:02.466 -> device unmounted
20:34:02.466 -> device unmounted
20:34:02.499 -> device unmounted
20:34:02.499 -> device unmounted
20:34:02.533 -> device unmounted
20:34:02.566 -> device unmounted
20:34:02.566 -> device unmounted
20:34:02.599 -> device unmounted
...
20:34:06.108 -> device unmounted
20:34:06.108 -> device unmounted
20:34:06.207 -> device unmounted
20:34:06.671 -> device mounted

Is it normal that void tud_umount_cb(void) callback is invoked so often as long as the device is not mounted again?

Its probably user fault. After setting flag on unmount which is returning false in tud_msc_test_unit_ready_cb it looks much better.

@chegewara no it is not, it should only be invoked once, which tinyusb stack you are testing with. Please make sure you run with this repo master. esp32s2 port currently doesn't seem to detect disconnection probably. From what I see, your version use Suspended for disconnected.

somewhat similar #564

Thanks, i will try to check with this repo. The iisue i have with my library on arduino esp32, which seems to be very far from original. Also it is version before 0.8.0 (with broken return value from tinyusb_init).

Like i described, it is in unmount loop as long as tud_msc_test_unit_ready_cb is returning true.
