What sort of USB controller does the X200s have? Is the controller
enabled for wakeup?
What happens with runtime suspend rather than S3 suspend?
It has the Intel Corporation 82801I (ICH9 Family) USB UCHI/USB2 EHCI
UHCI, not UCHI.
controller with PCI IDs 17aa:20f0/17aa:20f1. The hub is a Genesys Logic,
Inc. Hub with an ID of 05e3:0610 - this is an xHCI hub.
There is no such thing as an xHCI hub -- xHCI is a host controller
technology, not a hub technology. Perhaps you mean that it is a USB-3
hub.
Sorry but the record here is going to get a bit messy... But let's start
with a kernel with Huacai's patch.
=== Kernel + Huacai's Patch ===
1. If I plug in the external keyboard via the hub,
/sys/bus/usb/devices/usb1,
/sys/bus/usb/devices/usb1 is the root hub, which is an emulated device
that is closely tied to the host controller. The external Genesys Logic
hub is /sys/bus/usb/devices/1-1.
power/state is set to enabled. For the hub,
You mean power/wakeup, not power/state. In fact, there is no
power/state file for USB devices in sysfs.
Sorry for the typos and terminology issues above. You are correct on all
counts. Yes, I meant to say a USB 3.0 hub.
corresponding to usb1/1-1, power/wakeup is set to disabled.
2. If I plug the keyboard directly into the chassis, usb1/power/wakeup is
set to disabled, but usb1/1-1/power/wakeup is set to enabled.
Why is usb1/power/wakeup set to disabled? Doesn't Huacai's patch set it
to enabled?
No idea on my end either, I have double checked and that is indeed how
it is (and wakeup does work).
Is 1-1 the keyboard device? That is, did you plug the keyboard into the
port that the Genesys Logic hub was using previously?
The system wakes up via external keyboard plugged directly into the chassis
**or** the hub either way, regardless if I used S3 or runtime suspend (which
I assume to be echo freeze > /sys/power/state).
No. Runtime suspend has no relation to /sys/power. It is controlled by
/sys/bus/usb/devices/.../power/control. If you write "auto" to this
file for the device and for all the hubs above it (including the root
hub) then they will be put into runtime suspend a few seconds after you
stop using them, assuming no other USB devices are plugged into the same
hubs.
Got it.
On both unpatched and patched kernels, I have set power/control to
"auto" for both the root hub and the external hub and left the keyboard
for 60 seconds. Regardless if I plug the keyboard into the chassis or
the external hub, the keyboard continues to work from the first key
strike (no delay or lost input).
=== Kernel w/o Huacai's Patch ===
The controller where I plugged in the USB hub, /sys/bus/usb/devices/usb1 and
/sys/bus/usb/devices/usb1 is the root hub, not the controller. The two
are related but they are not the same thing. The controller is the
parent device of the root hub; it lies under /sys/bus/pci/devices/.
the hub, corresponding to usb1/1-1, their power/wakeup entries are both set
to disabled. Same for when I have the patch applied.
However, if I plug the external keyboard into the chassis, it would fail to
wakeup regardless of S3/runtime suspend (freeze). If I plug the external
keyboard via that USB Hub though, it would wake up the machine. The findings
are consistent between S3/freeze.
This means there's something different between the way the keyboard
sends its wakeup signal and the way the Genesys Logic hub sends its
wakeup signal.
Can you post the output from "lsusb -t" for this system?

Also, can you enable dynamic debugging for usbcore by doing:
echo module usbcore =p >/sys/kernel/debug/dynamic_debug/control
and then post the dmesg log for a suspend/resume cycle?
