Looking for Thunderbolt2 to USB 3 adaptor

[zarathu]

I have a MacBook Pro late 2013(IG model). It has only 2 USB 3 ports and 2 thunderbolt 2 ports. Its hard to find anything I need in thunderbolt at any reasonable price.

But I can't seem to find an adaptor which allows at least a 1-1 connection on the thunderbolt 2 ports on the side.

I'm sure they are out there. I just can't find them. Can anyone point me to some examples?

There's not much for demand for what you're looking for - I would guess that every computer that has a Thunderbolt 2 port has USB 3 ports and USB3 hubs are pretty inexpensive. The demand and requirements for any type of Thunderbolt cable, adapter or device is such that it's always more expensive than the USB counterpart.

That being said, there are TB2-to-USB3 devices:

https://www.amazon.com/Kanex-Thunderbolt-eSATA-plus-Adapter/dp/B00LOLBBQQ

Note that both have multiple output connections and both are about $75. I think the manufacturers believe that a single output (it sounds like that's what you may want) is not viable from a marketing standpoint.

You also might be able to use the Apple TB3-to-TB2 adapter (it's supposed to be bi-directional) and connect that to a TB3-to-USB3 adapter such as:

The problem with this approach is that the USB-C hub is a simple USB device. The Thunderbolt 2 port on the Mac side will expect a Thunderbolt 1/2 (or 3+adapter) device which this is not.

It's "compatible" with Thunderbolt 3 ports because USB protocol is always available on a TB3 port (alongside Thunderbolt, DisplayPort, and Power in some cases).

OP, Unfortunately there is alot of circuitry required to go from TB1/2/3 to anything. Think of these as tiny little PCI-e cards with their own chipset. Hence the high prices for the adapters you see.

Actually, in thinking about it, what I mentioned - the TB3-to-TB2, connector won't work because you have a male TB3 connector and the CableMatters device has a male TB3 connector as well. I don't know that a F-F TB3 connector exists.

I have also been looking for an answer to this question for a few weeks now and came across this thread. I think that the following may be more along the lines of what would be helpful to us:
