C-media Motherboards Driver

-->

Users who have motherboards with onboard audio (often with VIA, Realtek, or C-Media chipsets) may have issues with their audio or AC'97 errors in Device Manager. Often this is caused because the operating system was reinstalled and the motherboard chipset drivers were not installed. To resolve this issue, review the troubleshooting sections below.

Motherboards are EU Energy-related Products (ErP) ready, which requires products meet high efficiency standards with regards to energy consumption. This is in line with the ASUS vision of creating environmentally-friendly and energy-efficient products through design and innovation that reduce the carbon footprint of products and thus mitigate. The motherboards model is 'ASRock G41C-GS R2.0' and if anyone wants to have 1920x1080 resolutions in Windows10, with the onboard graphics you have to enable test mode to function properly. I don't think there is a way to override the digital signature for just one driver.

This topic is intended for OEMs who want to build a Windows 10 system with USB Type-C connector and want to leverage OS features that allow for faster charging, power delivery, dual role, alternate modes, and error notifications through Billboard devices.

A traditional USB connection uses a cable with a USB A and USB B connector on each end. The USB A connector always plugs in to the host side and the USB B connector connects the function side, which is a device (phone) or peripheral (mouse, keyboard). By using those connectors, you can only connect a host to a function; never a host to another host or a function to another function. The host is the power source provider and the function consumes power from the host.

The traditional configuration limits some scenarios. For example, if a mobile device wants to connect to a peripheral, the device must act as the host and deliver power to the connected device.

The USB Type-C connector, introduced by the USB-IF, defined in the USB 3.1 specification, addresses those limitations. Windows 10 introduces native support for those features.

Feature summary

Allows for faster charging up to 100W with Power Delivery over USB Type-C.
Single connector for both USB Hosts and USB Devices.
Can switch USB roles to support a USB host or device.
Can switch power roles between sourcing and sinking power.
Supports other protocols like DisplayPort and Thunderbolt over USB Type-C.
Introduces USB Billboard device class to provide error notifications for Alternate Modes.

Hardware design

USB Type-C connector is reversible and symmetric.

The main component are: the USB Type-C connector and its port or PD controller that manages the CC pin logic for the connector. Such systems typically have a dual-role controller that can swap the USB role from host to function. It has Display-Out module that allows video signal to be transmitted over USB. Optionally it can support BC1.2 charger detection.

Consider recommendations for the design and development of USB components, including minimum hardware requirements, Windows Hardware Compatibility Program requirements, and other recommendations that build on those requirements.Hardware component guidelines USB

Choose a driver model

Use this flow chart to determine a solution for your USB Type-C system.

If your system...	Recommended solution...
Does not implement PD state machines	Write a client driver to the UcmTcpciCx class extension. Write a USB Type-C port controller driver
Implements PD state machines in hardware or firmware and support USB Type-C Connector System Software Interface (UCSI) over ACPI	Load the Microsoft provided in-box drivers, UcmUcsiCx.sys and UcmUcsiAcpiClient.sys. See UCSI driver.
Implements PD state machines in hardware or firmware, but either does not support UCSI, or support UCSI but requires a transport other than ACPI	Write a client driver for the UcmCx class extension. Write a USB Type-C connector driver Write a USB Type-C Policy Manager client driver
Implements UCSI but requires a transport other than ACPI	Write a client driver to the UcmUcsiCx class extension. Use this sample template and modify it based on a transport that your hardware uses. Write a UCSI client driver

Bring up drivers

USB Function driver bring-up is only required if you support USB Function mode. If you previously implemented a USB Function driver for a USB micro-B connector, describe the appropriate connectors as USB Type-C in the ACPI tables for the USB Function driver to continue working.
For more information, see instructions about writing a USB Function driver.
USB Role-Switch driver bring-up is only required for devices that have a Dual Role controller that assumes both Host and Function roles. To bring-up the USB Role-Switch driver, you need to modify the ACPI tables to enable the Microsoft in-box USB role-switch driver.
For more information, see the guidance for bringing up the USB Role Switch Driver.
A USB Connector Manager Driver is required for Windows to manage the USB Type-C ports on a system. The bring-up tasks for a USB Connector Manager driver depend on the driver that you choose for the USB Type-C ports: The Microsoft in-box UCSI (UcmUcsiCx.sys and UcmUcsiAcpiClient.sys) driver, a UcmCx client driver, or a UcmTcpciCx client driver. For more information, see the links in the preceding section that describe how to choose the right solution for your USB Type-C system.

Test

Perform various functional and stress tests on systems and devices that expose a USB Type-C connector.

Test USB Type-C systems with USB Type-C ConnEx - Run USB tests included in the Windows Hardware Lab Kit (HLK) for Windows 10.

Run USB function HLK tests with a C-to-A cable (search for Windows USB Device in the HLK
