If BT operations (BREDR inquiry/LE scan) were triggered through the stack, followed by BT turn off through 'hciconfig hci0 down', the controller would still be active and consume power. Also, there is a possibility that a race condition/ synchronization issue might arise on the subsequent BT turn on, as the controller might try to push the events that were queued up before processing the HCI Reset command. btusb_shutdown_intel_new routine shall reset the controller and stop all BT operation. Advantages: 1. Power save on the platform 2. Host and controller will be in Sync.

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.
