ChromeOS version: 65.0.3325.209
USB devices: the peripherals are a logitech m-u0007 mouse and a KUL ES-87
keyboard plugged into an Acer B326HK monitor that is itself plugged into
this USB-C hub: https://mystuff.corp.google.com/stuff/items/1647. (Whew!)
Yes, the devices were connected when the Samus suspended.

I will file a feedback report next I see this. It repros reliably, so
should get it today unless I forget. :)

I just reproed and filed a feedback report. Not sure how to find it for you, though, but I referenced this bug in it.

Thanks for your feedback ... its here:

Do you happen to know make/model of the USB hub?

I do see this failure:


[ 9778.274586] PM: Device 1-3.1.3 failed to resume async: error -32

which might indicate there's some difficulties preventing keyboard (1-3.1.3 ... see below) or perhaps hub in general from providing wake caps.

[ 9778.945282] usb 1-3.1.3: New USB device found, idVendor=04d9, idProduct=a0b9
[ 9778.945292] usb 1-3.1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=17
[ 9778.945299] usb 1-3.1.3: Product: ES-87
[ 9778.945304] usb 1-3.1.3: Manufacturer: Keyed Up Labs

I'm guessing the mouse,

Bus 001 Device 033: ID 046d:c069 Logitech, Inc. M-U0007 [Corded Mouse M500]

Also fails to wake properly?

I'll try as well with a usb-c hub I know works to rule out any general regression on samus.

Sorry I missed the ref to mystuff URL w/ Apple USB-C A/V adapter in #1 ... ignore request in #3.

Just tried on samus (M65) with same dongle connected to keyboard (logitech) directly via USB-A as well as keyboard connected to monitor's (Dell U2410) USB hub and both successfully woke device in docked mode.

Need to see if I can track down the monitor next locally.  

Does your samus wake if the keyboard (or mouse) are directly connected to the Apple dongle?

Yes, the mouse also fails to work.

I haven't tried connecting directly to the dongle. It doesn't have enough
ports (only one USB-A) so I can't really work in that configuration to test
this. :-/

Would it be sufficient to plug into the dongle once the problem reproduces?
Or do you want me to let the machine fall asleep while the peripherals are
plugged in?

(Sorry, I mean, do you want me to let it fall alseep when they're plugged
into the hub directly, or would it be ok to switch the keyboard to the
USB-C hub once the device is asleep?)

Sounds like its likely to be an issue w/ hub inside the monitor but would be good to confirm its not apple dongle which also has at least 3 firmware versions I'm aware of.

If you could allow it to sleep with say just the keyboard connected to the apple dongle and confirm that it wakes we can focus on hub w/in the monitor.

Unfortunately I also just upgraded to a Pixelbook. Still have the Samus on
my desk, so let me see if I repro with the Pixelbook; if not, I will go
back to the Samus for regular usage. :)

OK, so Pixelbook + http://www.cablematters.com/pc-899-114-usb-c-to-4k-60hz-displayport-multiport-adapter.aspx (no monitor USB hub involved) still repros this. 

Interestingly, it seems to me (based on the caps-lock light) that the machine in fact stays on (with the screen off) *until* I hit the keyboard!

So what I observe:

1. I come back from getting some cookies. Screen is in power saving mode. 
2. I tap caps-lock key. Key lights up. 
3. I take some other keys. 
4. I tap caps-lock key a few seconds later. Key does not light up. 
5. Opening the lid of the Chromebook causes it to wake up; screen powers on, etc. 

#9: Mind filing another feedback report immediately after repro-ing this on the Pixelbook? Thanks!

Sure, will do when I am back in the office Monday. :)

Please comment on the bug after the report is filed. Thanks!

Sorry for the slow reply. I filed feedback just now, referencing this issue. I"m not sure how to track down the feedback report--I guess you can do that?

dmargolis:

If you filed the FR from your google.com account, check your Sent box in
Gmail. You should see your feedback report there. Copy and paste the listnr
link to this bug.

Oh, hah. Thanks.

dmargolis:

Is this the hub you have?
https://www.amazon.com/Cable-Matters-Multiport-Adapter-Ethernet/dp/B01M0K0DL2

Yep.

By the way, what keyboard are you using? Also, have you tried any different
keyboard?

It's a kul-es87. I've not tried another.

Should mouse work in the case it's the keyboard? I can try that (though I
don't think it does). Note that the keyboard may also be daisy chained into
the monitor and not directly into the hub. (I'm not at my desk but can
check later, if this matters.)

Please let me know which mouse you're using too.

It would be useful if you could draw a picture in keep or something that
shows how each device is attached to the USB tree.

Sure. Though I was wrong; the peripherals are plugged directly into the
hub.

So it looks like this:
