-Subject: [PATCH] Bluetooth: btusb: Add a Kconfig option to enable USB
- autosuspend by default
-
-On many laptops the btusb device is the only USB device not having USB
-autosuspend enabled, this causes not only the HCI but also the USB
-controller to stay awake, together using aprox. 0.4W of power.
-
-Modern ultrabooks idle around 6W (at 50% screen brightness), 3.5W for
-Apollo Lake devices. 0.4W is a significant chunk of this (7 / 11%).
-
-The btusb driver already contains code to allow enabling USB autosuspend,
-but currently leaves it up to the user / userspace to enable it. This
-means that for most people it will not be enabled, leading to an
-unnecessarily high power consumption.
-
-Since enabling it is not entirely without risk of regressions, this
-commit adds a Kconfig option so that Linux distributions can choose to
-enable it by default. This commit also adds a module option so that when
-distros receive bugs they can easily ask the user to disable it again
-for easy debugging.
