Echo Arena: $ 19.99 USD / Первые 3 месяца: БЕСПЛАТНО
- Если у вас есть учетная запись Oculus, вы сможете играть в Echo Arena, как только вы добавите ее в свою библиотеку Oculus.

- Благодаря спонсорской поддержке Intel, Echo Arena будет полностью бесплатной, чтобы все владельцы учетных записей Oculus постоянно добавляли в свою библиотеку Oculus в течение первых 3 месяцев после запуска (поэтому обязательно получите ее за это время)! После того, как эти 3 месяца закончились, это будет стоить 19,99 $, чтобы добавить в вашу библиотеку Oculus.

Если вы уже добавили Echo Arena в свою библиотеку Oculus, вам не нужно будет ее покупать; Вы уже владеете ей!

- Точная дата, которая заканчивается, будет распределена ближе к концу трехмесячного периода спонсорства.

- Echo Arena не включает доступ к Lone Echo; Вам нужно будет приобрести Lone Echo отдельно.

#Requires -Version 3.0
#Requires -RunAsAdministrator

# This script will disable all USB power saving settings on the system, in particular those associated with the Oculus Rift or Fresco Logic controllers.
# It should run fine on Windows 8, Windows 8.1 and Windows 10.
# If you have Windows 7, you will need to update Powershell first. Download and install (in order):
# 1: https://www.microsoft.…/details.aspx?id=42642
# 2: https://www.microsoft.…/details.aspx?id=40855

# To run:
# Save the script as 'OculusUSBfix.ps1' somewhere. Open the file's properties and check 'Unblock' and click Apply.
# Go to Start, Windows Powershell, right click and select 'Run as administrator'.
# Type 'Set-ExecutionPolicy RemoteSigned' once to be able to run PowerShell scripts (Or 'Set-ExecutionPolicy Unrestricted' if you did not unblock the file.)
# Go to the folder where you saved the script and run it.

# These are the USB hardware IDs that we want to disable the 'Allow the computer to turn off this device to save power' setting on.
# If you want to disable another USB devices power management, go to device manager, the properties of the device, details tab, Device ID / instance path, and copy the 'VID_nnnn&PID_nnnn' (Vendor ID and Product ID) to the following list. VID_2833 is Oculus VR LLC.
$DeviceIDs = (
"VID_2833&PID_0211", # Oculus Rift Sensor
"VID_2833&PID_0330", # Oculus Rift HMD
"VID_2833&PID_0031", # Oculus Rift HMD
"ROOT_HUB_FL30" # Fresco Logic xHCI (USB3) Root Hub
)


# The script starts here.
Write-Output "Starting script to fix Oculus Rift related USB power problems, and tune Fresco Logic USB settings."
Write-Output "This script will not check USB driver versions or fix any physical issues. If the problem persists, the following may help:"
Write-Output "- Check if you are running known good USB controller drivers or update them to a newer version."
Write-Output "- Mount the sensors right-side-up."
Write-Output "- Do not connect more than 2 sensors to the same USB controller on USB3 ports. Either use an extra card with USB3 ports, use USB2 ports, or use a USB2 extension cable."
Write-Output "- Test without USB and HDMI extension cables."
Write-Output "- Temporarily disconnect unneeded USB devices (The dongle for the Xbox controller is known to be bad about sharing the USB bus)."
Write-Output "- Close down any software that might be using the CPU in the background while you play. (Steam, Origin, Battle.net, Google Drive, Dropbox, etc.)."
