Hi,
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.
I am sorry, I am not sure what you wish to say here. Could you rephrase it?
from the default.
That connotation lid was closed represent human will not use laptop and
system must keep it was sleep and even though the laptop was
accidentally awakened.
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,
Well, no. We are talking about a kernel default. That needs to be so that it
always works on all systems. Convinience is secondary.
if system can doesn't consider lid open event and ignore the connotation
about lid open event I think that system behavior is inappropriate. you
don't think my patch was inapproriate that on some system doesn't
consider lid open event.
In additon, if it doesn't include my patch and non-keyboard hid device
doesn't make system wakeup by ohci. because ohci driver doesn't export
wakeup property for usb slave device.
if you don't think so and I think HID definition is ridiculous.
It does have its weaknesses, in particular with respect to differentiating
between events for wakeups. But we cannot change it.
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
If you deviate from the default, you deviate. That is reducing the number of
changes is worth little. The default must be above everything else safe.

bios and kernel was two sets of things and they should has their own
indepdent configuration. if bios enable usb wakeup but wakeup is still
not work well. Do you think it is appropriate?
in additon, The keyboard device is enabled by default, and other hid
devices should also be enabled. Otherwise, it will be treated differently.
