For all devices except 'Mass Storage' Devices: If you plug a device to one USB port, and then you plug the same device to another USB port, a new record of the same device will be created for each USB port that you plug. So if you see multiple lines for exactly the same device, it means that you plugged it to different USB ports.

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.

Testo Smart Apps allow creation of concise reports quickly, that can be saved online or sent via e-mail. Connecting to a variety of testo devices and Smart Probes, we have apps for any application. Some apps, such as the testo Thermography app, act as a secondary screen allowing for live feedback from the camera.

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

Testo Port Devices Driver Updater

  • 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.

Official specifications

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

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.
