From 5f677f1d45b2bf08085bbba7394392dfa586fa8e Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 2 Apr 2010 13:20:11 -0400 Subject: [PATCH] USB: fix remote wakeup settings during system sleep MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This patch (as1363) changes the way USB remote wakeup is handled during system sleeps. It won't be enabled unless an interface driver specifically needs it. Also, it won't be enabled during the FREEZE or QUIESCE phases of hibernation, when the system doesn't respond to wakeup events anyway. Finally, if the device is already runtime-suspended with remote wakeup enabled, but wakeup is supposed to be disabled for the system sleep, the device gets woken up so that it can be suspended again with the proper wakeup setting. This will fix problems people have reported with certain USB webcams that generate wakeup requests when they shouldn't, and as a result cause system suspends to fail.
