Breakthrough For Many Issues: 'UserModePowerService'

Remember our friend '[DisplayManager] Failed to set power mode on NVidia adapter. -175
' ??

If users check Windows Event Viewer and select 'Windows Logs/System' they will discover numerous messages referring to 'Process C:\Program Files\Oculus\Support\oculus-runtime\OVRServer_x64.exe (process ID:3556) reset policy scheme from {*****************************} to {******************************}

This is a deliberate decision by the developers in how OR configures the power for the headset, essentially, a combination of Windows and the hmd are constantly resetting the power policy to protect the life of the lens and save energy, unfortunately for us this causes many of the 'driving me crazy' disconnection issues. Now, Windows should not constantly be resetting power policy in reference to any device but (under instruction from the OR software) the OS does esp in Windows 7, 8 and 10, when that happens you can guarantee HDMI or Sensor disconnects.

So, with this in mind what we are going to do is force Windows to set one power policy and keep it, thereby preventing the vast majority of 'HDMI and usb sensor disconnects'

Go into your Windows power option settings and select 'High Performance', then 'advanced' and look for the USB settings, change 'Sleep mode' from enabled to Never.
2: In the Run Box bar type 'cmd', a window will appear, in that window type: POWERCFG -LIST
If you look you will see the different power plans listed and the one you just set called 'high performance'  with an asterisk next to it (indicating that this power plan is active) right click and copy the GUID (that series of numbers associated with the high performance setting) ) line, open notepad and paste, then save it somewhere on your desktop. 

Use-Specific-Power-Plan

3:  In the run box type: gpedit.msc, this opens the Local Group Policy Editor which will force windows to keep the performance plan that the Rift MUST have i order to work correctly.

In the left pane, navigate here:

Computer Configuration -> Administrative Templates -> System -> Power Management


Specify a custom active power plan


4. In the right pane of the window shown above, double click Specify a custom active power plansetting which is Not Configured by default to get this:


Use-Specific-Power-Plan-2

5. In the above shown window, firstly click Enabled and then in the Options section, input the Custom Active Power Plan (GUID) as we copied from step 1. Click Apply followed by OK. You may close the Local Group Policy Editor now. 

6: When you go back into Power Options you should see this:

Finally, if you go back into Event Viewer and select 'Windows Logs/System' you should see:

See the top one?

(Also, note underneath the top one you can see OR Home is resetting the power policy every three seconds, no wonder people are getting hdmi and sensor disconnects!)

After this, you should never see a single error associated with 'UserModePowerService'

edit. Asmedia have released a new usb driver in the lsat couple of weeks, I installed them and the problem remains if you allow Windows OS and Oculus software to constantly reset the power policy. I recommend the above policy to force Oculus Home to stop resetting and causing disconnects.

Most of us have no use for PRO so this is a extremely niche fix.

While the post above does certainly seem like self promotion, it does also seem to be on topic. If the poster continues to post links to their site I will look into it further, but one link is OK.
