OWC doesn't show the TB3 docks as being compatible with any TB2 computer. Issue is how many of the ports would work? Does dock rely on TB3's USB3 channel or does it create its own for USB ports?
I bought one last year when on sale. Now I look and everything is TB3 or USB-C and only can find it on the support pages. Usually OWC supports older Macs and provides lots of options. What's going on with this?
Based off this clue I am going to try and connect a Western Digital 4TB Passport that uses a USB 3.1 Micro B 10 pin into the drive and a USB 3.1 regular connector, attach a USB 3.1 female/female connector, then a USB 3.1 male/USB-C female adapter, the Apple TB3 to TB 2 in reverse, and a TB 2 cable to the Pro. Wish me luck. Why do this, so I can use some of the five unused TB2 powered ports and leave some powered USB ports open on the rear of the Pro. Drive costs $100, adapters cables cost $75, still $50 cheaper than a TB3 4TB portable without trying to get TB2 connection.You can interface with Thunderbolt 3 devices, albeit at Thunderbolt 2 speeds, using Apple's Thunderbolt 3 to 2 adapter in reverse (https://www.apple.com/ca/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter). Thus with that compatibility, why would they keep a legacy toolset going?
Don't think it will work. Going from TB2 to TB3 does not get USB. What should work is a TB2 to USB adapter similar to https://www.amazon.com/Kanex-Thunderbolt-eSATA-plus-Adapter/dp/B00LOLBBQQ - still USB at 3.0 speeds (5gbs).Based off this clue I am going to try and connect a Western Digital 4TB Passport that uses a USB 3.1 Micro B 10 pin into the drive and a USB 3.1 regular connector, attach a USB 3.1 female/female connector, then a USB 3.1 male/USB-C female adapter, the Apple TB3 to TB 2 in reverse, and a TB 2 cable to the Pro.

Correct. Mine was a fail BECAUSE the Apple USB-C to Thunderbolt 2 is NOT REVERSIBLE, contrary to claims elsewhere. I buy the adapter suggested above. THanks for your help.Don't think it will work.

Still lots of confusion as there is no USB-C to Thunderbolt 2 adapter. It is Thunderbolt 3 that shares the same physical connector as USB-C.Correct.
