USB ports are turned on by the firmware as it looks for disks to boot, ensure that they aren't power cycled before the xHCI driver comes up. This enables USB devices to be ready for use faster and reduces wear and risk of data loss on storage devices. A particularly annoying case was booting from a mechanical disk, which takes time to spin up again. Vendor kernel also kept these ports powered, and by the same means.

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 reStructuredText 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.
