[PATCH] USB: quirks: Ignore wakeup from the Valve Index HMD hub
Posted by Curtis Vogt 9 hours ago
The Valve Index HMD's onboard USB hub (28de:2613) asserts remote wakeup a
few seconds after the host enters S3, so a system with the headset
attached does not stay suspended. Observed on 7.3-rc2: every suspend
attempt returned after ~6 seconds with wakeup events recorded from the
hub. Disabling wakeup on the hub through sysfs allows the host to stay
asleep until woken from the front panel. The headset most likely reacts to
the DisplayPort link being taken down as the host suspends.

Nothing behind this hub is a device that should be able to wake the host.
The headset includes a radio, microphone, and a downstream Microchip
USB2744 hub.
