From 5d9d01a30204c99edf99189018953ee84c5f5017 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Thu, 11 Oct 2012 02:50:10 +0000 Subject: usbnet: Support devices reporting idleness Some device types support a form of power management in which the device suggests to the host that the device may be suspended now.
