Do standard rectangle USB to Thunderbolt 2 cables exist? Do standard rectangle USB to Thunderbolt 2 cables exist?
I want to use my Thunderbolt 2 ports to connect a standard USB hub.
Thanks!
Thunderbolt 2 is an active connector so even though USB is able to be embedded in the data lines, you would need a full thunderbolt chip to establish that link.

Kanex makes amazingly reliable and fairly priced hardware in my experience:

Also, look for used or fire sale full docks, since they are much less expensive now that Thunderbolt3 / USB 4 is the new hotness for adapters and docks - the older ones might be available as people upgrade to the latest.
