It looks like the 6 prong is a firewire interface. I would check for other options besides usb. If you use a desktop, you can probably add a firewire interface card. Most new laptops have usb c or thunderbolt ports which may support the higher speed of firewire better than older usb ports.
I looked into this several years ago and found there is no adapter that will work. The technical explanation is that Firewire is a continuous feed while USB is not. You can still get a Firewire adapter for your desktop. I use mine with VueScan software for the driver on Windows 10.
