From e0386cf2809219bbdd30895f46f1f567b56902b6 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Fri, 25 May 2012 10:27:25 -0400 Subject: [PATCH 1/1] rules: Limit USB autosuspend on USB HID devices Some USB ports on external hubs may be reported as "fixed". We only want to auto-enable this on ports that are internal to the machine, so check the parent state as well. --- rules/42-usb-hid-pm.rules | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/rules/42-usb-hid-pm.rules b/rules/42-usb-hid-pm.rules index d5d5897c3..9e5f59fc6 100644 --- a/rules/42-usb-hid-pm.rules +++ b/rules/42-usb-hid-pm.rules @@ -46,4 +46,10 @@ ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="04b3", ATTR{idProduct}=="4012 ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="14dd", ATTR{idProduct}="0002", TEST=="power/control", ATTR{power/control}="auto" # USB HID devices that are internal to the machine should also be safe to autosuspend + +ACTION=="add", SUBSYSTEM=="usb", SUBSYSTEMS=="usb", ATTRS{removable}=="removable", GOTO="usb_hid_pm_end" +ACTION=="add", SUBSYSTEM=="usb", SUBSYSTEMS=="usb", ATTRS{removable}=="unknown", GOTO="usb_hid_pm_end" + ACTION=="add", SUBSYSTEM=="usb", ATTR{bInterfaceClass}=="03", ATTRS{removable}=="fixed", TEST=="../power/control", ATTR{../power/control}="auto" + +LABEL="usb_hid_pm_end" \ No newline at end of file -- 2.30.2
