The Thunderbolt 3 specification says it's backward compatible with the older Thunderbolt 2. But more than one manufacturer has said that its Thunderbolt 3 peripherals are not compatible.
The reason seems to be twofold; first, some early USB-C controller chips seem to have a backward compatibility issue; and second, a Thunderbolt 3 peripheral, while using a Thunderbolt 3 port, isn't actually using the Thunderbolt data channels; instead, it's making the connection over the USB 3.1 Gen 2 channels. Thunderbolt 2 was never compatible with USB, so this arrangement, even with an adapter, won't work.
