USB 3 adapters for Thunderbolt 2 ports in Mac Pro late 2013?

Thanks! I don't have any bare SATAs ... My external drives are the plug-in type.

I visited OWC and ended up with a basic USB 3 dock. I will put the wired mouse and keyboard there.

The empty Thunderbolt 2 ports will remain a testament to technical obsolescence.

Thanks again, BDAqua and Grant. I had never paid any attention to the two USB ports in the wired keyboard. Now my classic A1152 mouse is happily drawing power from the keyboard. I have a stack of these that I bought used on eBay. Most die by strain on the cord insertion point.

I use one USB port for all sorts of devices, and the only devices that have had difficulty with it are the external hard drives (4T and 6T). For these, I have to switch ports. Now I bought enough port life to outlive the useful life of the late 2013, or the owner.

Thanks! Some quick research shows that there are off-brand Bluetooth-compatible mice in the teens, while the Apple mouse is in the seventies. Does it make a difference?

Thanks, BDAqua, be safe out there.
