Hi, I am A. Stevens here to help with your question!
Hi Chris - Let me located a suitable driver for your S5 for Linux.
You can follow this guide...it's written for an S2, but same concept. Android platform.
Another option that might be simpler would be to get a MicroSD card and transfer your photos there first. Then connect the card to your computer via a card reader and copy the photos.
