-Subject: [PATCH v2] platform/x86: asus-wmi: disable USB0 hub on ROG Ally
- before suspend
-
-ASUS have worked around an issue in XInput where it doesn't support USB
-selective suspend, whcih causes suspend issues in Windows. They worked
-around this by adjusting the MCU firmware to disable the USB0 hub when
-the screen is switched off during the Microsoft DSM suspend path in ACPI.
-
-The issue we have with this however is one of timing - the call the tells
-the MCU to this isn't able to complete before suspend is done so we call
-this in a prepare() and add a small msleep() to ensure it is done. This
-must be done before the screen is switched off to prevent a variety of
-possible races.
-
-Without this the MCU is unable to initialise itself correctly on resume.
