Vampire Mice: How USB PM Impacts You
Session information has not yet been published for this event.
One Line Summary
The first part of the talk targets users of all skill levels, and the second part of the talk will be a developer-focused discussion on creating new tools for crowd-sourced USB power management testing. Systemd, udev, Linux distros, and kernel developers should participate in this conversation.
Abstract
Did you know that your innocent USB mouse is actually a power-hungry battery-draining monster? This talk explores the impact of USB devices on platform power consumption, along with current (and future) tools to tame the monster. USB devices have always been battery eaters, keeping the whole platform in higher power states, including CPUs and chipsets. The aim of this talk is to educate users and developers on how USB devices impact their battery life, and start a discussion on how the Linux community can improve USB power management.
