Hi,

Lid events are necesarily for the whole system.

and for laptop usb wakeup that as general ask bios to enable usb
wakeup then if need do more things to enable usb wakeup I think this
usb wakeup function isn't friendly and inconveient, so enable it by
default.
after add this patch, if want to use usb wakeup function it only need
enable bios configure it think it is appropriate.

No. If you wish your laptop to be resumed by USB events, that is one thing.
You can alter the system settings. That must work. But it is a different
issue
Hi Oliver,

if you only talk about wakeup source you can think that usb-wakeup source and acpi-lid wakeup source was different things. but if you talk about laptop and distinguish lid and other event and you shoud know the cannotation why system still continue sleep when lid closed then system by other event wakeup. if you need test usb-wakeup for laptop and that lid shouldn't be closed.

from the default.

In general any HID device must have wakeup capability to be usable for
selective suspend. You cannot draw conclusions from that.
you still can has wakeup capability, but it should be keep enabled by default. because the hid device should be convenient for human, if you don't think so and I think HID definition is ridiculous.

In addition, I had said that laptop usb wakeup was disabled in system bios by default and if user want enable usb wakeup that was only by configure bios and doesn't need enable wakeup node if my patch was applied
