Laptop won't wake from USB or will wake up immediately

in flag

I have a USB keyboard at /sys/bus/usb/devices/1-1.3 - where /sys/bus/usb/devices/1-1 is a hub. I'd like to be able to wake the laptop up using this keyboard, without opening the lid (currently opening the lid does wake correctly).

In this setup, keyboard does not perform wakeup:

# grep . /sys/bus/usb/devices/{usb1,1-1,1-1.3}/power/wakeup
/sys/bus/usb/devices/usb1/power/wakeup:disabled
/sys/bus/usb/devices/1-1/power/wakeup:enabled
/sys/bus/usb/devices/1-1.3/power/wakeup:enabled

However, if I enable power/wakeup for usb1 as well, the laptop immediately wakes up after going to sleep, without any input. I've tested this with a couple of keyboards.

How can I debug this?

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
