[ Upstream commit 27c2ca90e2f34cd3c4849af996e1a96a69e700d3 ]
The rb2 only has a single USB controller, it can be switched between a
type-c port and an internal USB hub via a DIP switch. Until dynamic
role switching is available it's preferable to put the USB controller
in host mode so that the type-A ports and ethernet are available.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
