We only want to auto-enable this on ports that are internal to the machine, so check the parent state as well. --- Sorry, screwed up the label name on the first version. 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 d5d5897..9e5f59f 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 -- 1.7.10.2
