Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device. In Windows 10, the driver has been rewritten by using the Kernel-Mode Driver Framework that improves the overall stability of the driver. Improved PnP and power management by the driver (such as, handling surprise removal). Click Browse and locate the USB driver folder. (The Google USB Driver is located in androidsdk extras google usbdriver.) Click Next to install the driver. Or, to upgrade an existing Android USB driver on Windows 7 and higher with the new driver: Connect your Android device to your computer's USB port.
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. Wincomm driver download for windows 10. 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.
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
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.
Download vendor driver software. 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.

STMicroelectronics Pioneers Smaller and Faster Chargers
and Power Supplies with World’s First Driver and GaN Device
- World’s first solution to integrate Si driver and GaN power transistors in one package
- Enables chargers and adapters 80% smaller and 70% lighter, while charging 3 times faster compared to ordinary silicon-based solutions
Geneva, September 30, 2020 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has unveiled MasterGaN®, the world-first platform embedding a half-bridge driver based on silicon technology along with a pair of gallium-nitride (GaN) transistors. The combination will accelerate the creation of next-generation compact and efficient chargers and power adapters for consumer and industrial applications up to 400W.
GaN technology enables these devices to handle more power even as they become smaller, more lightweight, and more energy efficient. These improvements will make a difference for smartphone ultra-fast chargers and wireless chargers, USB-PD compact adapters for PCs and gaming, as well as in industrial applications like solar-energy storage systems, uninterruptible power supplies, or high-end OLED TVs and server cloud.
Today’s GaN market is typically served by discrete power transistors and driver ICs that require designers to learn how to make them work together for best performance. ST’s MasterGaN approach bypasses that challenge, resulting in faster time to market and assured performance, together with a smaller footprint, simplified assembly, and increased reliability with fewer components. With GaN technology and the advantages of ST’s integrated products, chargers and adapters can cut 80% of the size and 70% of the weight of ordinary silicon-based solutions.
“ST’s market-uniqueMasterGaN platform builds on our proven expertise and power-design skills to combine high-voltage smart-power BCD process with GaN technology, to accelerate the creation of space-saving and power-efficient products that are kinder to the environment,” said Matteo Lo Presti, Executive VP and General Manager Analog Sub-Group, STMicroelectronics.
ST is launching the new platform with MasterGaN1, which contains two GaN power transistors connected as a half bridge with integrated high-side and low-side drivers.
MasterGaN1 is in production now, in a 9mm x 9mm GQFN package only 1mm high. Priced at $7 for orders of 1,000 units, it is available from distributors.
An evaluation board is also available to help jump-start customers’ power projects.
Further technical information:
The MasterGaN platform leverages STDRIVE 600V gate drivers and GaN High-Electron-Mobility Transistors (HEMT). The 9mm x 9mm low-profile GQFN package ensures high power density and is designed for high-voltage applications with over 2mm creepage distance between high-voltage and low-voltage pads.

The family of devices will span different GaN-transistor sizes (RDS(ON)) and will be offered as pin-compatible half-bridge products that let engineers scale successful designs with minimal hardware changes. Leveraging the low turn-on losses and absence of body-diode recovery that characterize GaN transistors, the products offer superior efficiency and overall performance enhancement in high-end, high-efficiency topologies such as flyback or forward with active clamp, resonant, bridgeless totem pole PFC (power factor corrector) and other soft- and hard-switching topologies used in AC/DC and DC/DC converters and DC/AC inverters.
The MasterGaN1 contains two normally-off transistors that feature closely matched timing parameters, 10A maximum current rating, and 150mΩ on-resistance (RDS(ON)). The logic inputs are compatible with signals from 3.3V to 15V. Comprehensive protection features are also built in, including low-side and high-side UVLO protection, interlocking, a dedicated shutdown pin, and over-temperature protection.
