From a7cd740b64bfea2e841e646cc495738fccb92950 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Felix=20D=C3=B6rre?= Date: Sat, 6 Jul 2024 20:46:51 +0000 Subject: [PATCH] usb-device: Allow signaling capability of remote_wakeup. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To use this feature you need to create a usb device signaling remote wakeup and then enable remote wakeup on the host (on linux write enabled to /sys/bus/usb/devices//power/wakeup). Then you can wake up the host when is on standby using USBDevice.remote_wakeup.
