From 5e35287b2bfc877558acc9ad67aca7ace01021e8 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 2 Apr 2010 13:21:33 -0400 Subject: [PATCH] USB: don't enable remote wakeup by default commit 7aba8d014341341590ecb64050b7a026642a62eb upstream. This patch (as1364) avoids enabling remote wakeup by default on all non-root-hub USB devices. Individual drivers or userspace will have to enable it wherever it is needed, such as for keyboards or network interfaces. Note: This affects only system sleep, not autosuspend. External hubs will continue to relay wakeup requests received from downstream through their upstream port, even when remote wakeup is not enabled for the hub itself. Disabling remote wakeup on a hub merely prevents it from generating wakeup requests in response to connect, disconnect, and overcurrent events.
