After reboot already attached USB is not get MOUNT event in IMX8mp Android 11

[Lavanyavijay]

Dear NXP Team,

I'm encountering an issue with automatic USB device mounting on my IMX8MP board running AOSP Android 11.

Scenario:

1. Before Reboot:

   • I connect a USB pendrive to the board.

2. After Reboot:

   • The USB device is detected (ATTACH event is received).
   • However, the MOUNT event is not triggered, and the Vold service is not called. but is the pendrive is mounted and accessible to the system.

Request:

I would appreciate your assistance in identifying the cause of this problem and understanding how to ensure the USB pendrive notifies the mount event after a system reboot.

Additional Information

• Have you encountered similar issues with USB device mounting on the IMX8MP platform?
• Are there any known configuration options or workarounds to receive the mounting events in this scenario?

Please find an attachment for the LOGS
The USB mount notification only works after a system reboot. When the pen drive is attached before booting, the mount happens silently.

./base/packages/SystemUI/src/com/android/systemui/usb/StorageNotification.java
not to be called with state :
case VolumeInfo.STATE_MOUNTED:
case VolumeInfo.STATE_MOUNTED_READ_ONLY:

Hello,

Could you please try adding unmount before disconnecting the device?

Best regards.
