All equipment facilities installed on ASUS P8H67 are listed below. In order to facilitate the search for the necessary driver, choose one of the Search methods: either by Device Name (by clicking on a particular item, i.e. Intel(R) C200 Series Management Engine Interface - 1C3A) or by Device ID (i.e. PCI VEN8086&DEV1C3A). Specifications Winchiphead CH340 / CH341 / HL340 driver. The Prolific Winchiphead CH340 / CH341 / HL340 Serial Driver for Apple Mac OS X driver is the reliable interface between your CH340 / CH341 / HL340 based cable and your Mac. The driver supports many CH340 / CH341 / HL340 based dongles and USB interfaces, like clone Arduino’s.
Method 2: uninstall the WIA Driver. Repeat step 1 mentioned in the previous method. Choose Device Manager from the menu. Find Imaging devices from the list and expand it. (If you can't find this item, please try to show it by clicking View tab selecting Show hidden devices.) Confirm which your scanner device is and right click on it.
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. Trackman course list. 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.

If a multifunction PCI device conforms completely to the PCI multifunction standard, the PCI bus driver enumerates the individual functions. The PCI bus driver manages the fact that there is more than one function residing at a single device location. To the rest of the system, the individual functions operate like independent devices.
Vendors of a PCI multifunction device on an NT-based platform must do the following:
Ensure that the device conforms to the PCI multifunction specification.
Provide a PnP function driver for each function of the device.
Since the system-supplied bus driver handles the multifunction semantics, the function drivers can be the same drivers that would be used if the functions were packaged as individual devices.
Provide an INF file for each function of the device.
The INF files can be the same files that would be used if the functions were packaged as a individual devices. The INF files do not need any special multifunction semantics.
For example, the following figure shows the sample device stacks that might be created for a multifunction PCI device with ISDN and modem functions.
As shown in the previous figure, rather than enumerating one multifunction device, the PCI driver enumerates two child devices. The PnP manager treats each child device like a typical device, locating INF files, loading the appropriate drivers, calling their AddDevice routines, and so forth until a device stack is created for each device. The PCI driver arbitrates the resources for the child devices and manages any other multifunction aspects of the device. The vendor of the multifunction card provides function drivers and INFs for the ISDN and modem devices, just as if they were separate devices.

The illustration focuses on the function driver and bus driver for each function and their associated FDO and PDO. Any filter drivers (and filter DOs) are omitted for simplicity.
