What happened ?
If an application uses
tuh_cdc_mounted()to check whether a CDC device is mounted, it will be reported "true" before the process config is completed.The application could then disrupt the process config or the application would not yet be able to work with the CDC device.
tuh_cdc_mount_cb()is correctly called inset_config_complete()after the process config has been completed.the hid host may have the same issue...
How to reproduce ?
