 ## Examples
 * [**examples/SimpleStorageWriteRead**](https://github.com/arduino-libraries/Arduino_UnifiedStorage/blob/main/examples/SimpleStorageWriteRead/SimpleStorageWriteRead.ino) - Write/read simple data from SD, USB and internal storage
 * [**examples/AdvancedUSBInternalOperations**](https://github.com/arduino-libraries/Arduino_UnifiedStorage/blob/main/examples/AdvancedUSBInternalOperations/AdvancedUSBInternalOperations.ino) - Navigate file structure and demonstrate file operations between USB and internal storage
-* [**examples/PortentaH7Logger**](https://github.com/arduino-libraries/Arduino_UnifiedStorage/blob/main/examples/PortentaH7Logger/PortentaH7Logger.ino) - Log analog input to the Portenta H7  with timestamp, then save to internal storage and backup to USB (if detected) 
 * [**examples/BackupInternalPartitions**](https://github.com/arduino-libraries/Arduino_UnifiedStorage/blob/main/examples/BackupInternalPartitions/BackupInternalPartitions.ino) - Back up all partitions on the internal storage to a USB Mass Storage device.
 
 ## Instructions

 * Portenta C33 + Vision Shield: SD and QSPI
 * Opta: Internal QSPI Flash and USB
 
+
+Note: Due to an unforeseen compatibility issue on the Portenta Breakout Board, inserting a USB drive on the USB-A port of the breakout board may occasionally cause a reboot on Portenta C33 boards. You can work around this issue by connecting your USB Mass Storage device through a USB hub. This limitation only affects Portenta C33 boards.
