If I recall correctly, its this:

The Yocto reference BSPs themselves are about exercising core
functionality on easily available h/w references (one per major arch).

Those reference BSPs are on the Yocto release kernel (which is now
typically LTSI kernel), and hence have all the Yocto kernel features
(union filesystems, optional preempt-rt support, CVEs, -stable updates,
etc) and configuration meta-data (base policy + configuration fragemnt
support).

We try and make them as functional as possible, but sticking with the
stable and longer term kernels means that development which happens
on the latest mainline, or different community trees is only merged to
the Yocto kernel if we get explicit support and patches ported. That
means that some bleeding edge, or advanced functionality is available
in those feature-full and community supported trees.

The layer I pointed at above, has that mix of extended/enhanced
functionality.

We refreshed the the ARM reference to the beaglebone black in the latest
Yocto release, and thanks to TIs (via DenysD) support .. we have a
mainline supported, and very functional refernece.

That being said, working USB is core functionality and it was tested
green for the 1.5 release .. at least if my memory serves. So it
should be working in your build.
