Just one query. Even if it wakes up after closing the lid and removing the mouse, wouldn't pm suspend be triggered again later by the system once it sees that usb is also good to be suspended again ? I presume a laptop form factor would be having this facility of re-trigerring suspend. Let me know if this is not the case.
No, we generally don't use opportunistic suspend (e.g. unlike android) so the laptop will not suspend again.
So this is an actual bug affecting, for example, the Lenovo ThinkPad X13s.
Thanks for the clarification. I was thinking in android perspective only. But if we don't wake up the system upon disconnect, wouldn't the controller still be under the assumption that device is connected when it is actually not and only realise this when we resume later ?
Correct.
