Okay...

....While you're awaiting someone to join iMore and offer the exact solution you're looking for, feel free to try USB drive apps like Phone Drive, or Goodreader. You can also upload your photos and videos to cloud services like Dropbox, box, Google Drive, iCloud Drive and then download them to your PC.
