| Subject: USB: don't enable remote wakeup by default |
| |
| From: Alan Stern <stern@rowland.harvard.edu> |
| |
| 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. |
