  • If the file system is NTFS or exFAT, you should format your USB storage device to FAT32 to make it recognizable for OTG. Follow the instructions below to format your USB drive to FAT32.
  • If the file system is FAT32 but the OTG still cannot detect it, try another USB drive to see if it works. If other USB drive works normally, maybe your original flash drive is corrupted or damaged. Just change it.
