The product page for the Developer Strap requires you to be logged into a U.S. Apple Developer account, but it’s linked from the public VisionOS developer resources page:
The Developer Strap is an optional accessory that provides a USB-C
connection between Apple Vision Pro and Mac and is helpful for
accelerating the development of graphics-intensive apps and games.
The Developer Strap provides the same audio experience as the
in-box Right Audio Strap, so developers can keep the Developer
Strap attached for both development and testing.
Unclear whether the USB-C port on the Developer Strap allows you to connect peripherals like external storage devices. I suspect not. But MacRumors’s Aaron Perris uncovered evidence that this strap can be used for troubleshooting and diagnostic purposes.
