USB Class Drivers MCCI offers a comprehensive line of USB class drivers for popular operating systems, including Windows, macOS, Linux, Green Hills INTEGRITY OS, FreeRTOS, RTEMS, eCos, VxWorks, and QNX. These drivers can also be used with our TrueTask USB embedded USB host stack to support any operating system (even bare metal).
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).
- Added power management features such as USB Selective Suspend.
In addition, UWP applications can now use the APIs provided by the new Windows.Devices.SerialCommunication namespace that allow apps to talk to these devices.
Usbser.sys installation
Load the Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.
Note Download ndta driver.
If you trying to install a USB device class driver included in Windows, you do not need to download the driver. They are installed automatically. If they are not installed automatically, contact the device manufacturer. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows.
Windows 10
In Windows 10, a new INF, Usbser.inf, has been added to %Systemroot%Inf that loads Usbser.sys as the function device object (FDO) in the device stack. If your device belongs to the Communications and CDC Control device class, Usbser.sys is loaded automatically.You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.
USBClass_02
USBClass_02&SubClass_02
- If you want to load Usbser.sys automatically, set the class code to 02 and subclass code to 02 in the Device Descriptor. For more information, see USB communications device class. With this approach, you are not required to distribute INF files for your device because the system uses Usbser.inf.
- If your device specifies class code 02 but a subclass code value other than 02, Usbser.sys does not load automatically. Pnp Manager tries to find a driver. If a suitable driver is not found, the device might not have a driver loaded. In this case, you might have to load your own driver or write an INF that references another in-box driver.
- If your device specifies class and subclass codes to 02, and you want to load another driver instead of Usbser.sys, you have to write an INF that specifies the hardware ID of the device and the driver to install. For examples, look through the INF files included with sample drivers and find devices similar to your device. For information about INF sections, see Overview of INF Files.
Note
Microsoft encourages you to use in-box drivers whenever possible. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Unlike desktop editions, it is not possible to load a driver through an external driver package. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.
Windows 8.1 and earlier versions
In Windows 8.1 and earlier versions of the operating system, Usbser.sys is not automatically loaded when a USB-to-serial device is attached to a computer. To load the driver, you need to write an INF that references the modem INF (mdmcpq.inf) by using the Include directive. The directive is required for instantiating the service, copying inbox binaries, and registering a device interface GUID that applications require to find the device and talk to it. That INF specifies 'Usbser' as a lower filter driver in a device stack.
The INF also needs to specify the device setup class as Modem to use mdmcpq.inf. Under the [Version] section of the INF, specify the Modem and the device class GUID. for details, see System-Supplied Device Setup Classes.
For more information, see this KB article.
Configure selective suspend for Usbser.sys
Starting in Windows 10, Usbser.sys supports USB Selective Suspend. It allows the attached USB-to-serial device to enter a low power state when not in use, while the system remains in the S0 state. When communication with the device resumes, the device can leave the Suspend state and resume Working state. The feature is disabled by default and can be enabled and configured by setting the IdleUsbSelectiveSuspendPolicy entry under this registry key:
To configure power management features of Usbser.sys, you can set IdleUsbSelectiveSuspendPolicy to:
'0x00000001': Enters selective suspend when idle, that is, when there are no active data transfers to or from the device.
'0x00000000': Enters selective suspend only when there are no open handles to the device.
That entry can be added in one of two ways:
Write an INF that references the install INF and add the registry entry in the HW.AddReg section.
Describe the registry entry in an extended properties OS feature descriptor. Add a custom property section that sets the bPropertyName field to a Unicode string, 'IdleUsbSelectiveSuspendPolicy' and wPropertyNameLength to 62 bytes. Set the bPropertyData field to '0x00000001' or '0x00000000'. The property values are stored as little-endian 32-bit integers.
For more information, see Microsoft OS Descriptors.
Develop Windows applications for a USB CDC device
If you install Usbser.sys for the USB CDC device, here are the application programming model options:
Starting in Windows 10, a Windows app can send requests to Usbser.sys by using the Windows.Devices.SerialCommunication namespace. It defines Windows Runtime classes that can use to communicate with a USB CDC device through a serial port or some abstraction of a serial port. The classes provide functionality to discover such serial device, read and write data, and control serial-specific properties for flow control, such as setting baud rate, signal states.
In Windows 8.1 and earlier versions, you can write a Windows desktop application that opens a virtual COM port and communicates with the device. For more information, see:

TrueTask USB is MCCI’s portable embedded USB host stack and USB platform. It supports USB 3.2, USB 2.0 and USB 1.1 host controllers, as well as USB 3.2, 2.0 and 1.1 hubs. It supports all speeds from low speed USB to 10 Gbps SuperSpeed Gen2. It has been tested at the USB-IF PIL as part of xHCI certification in multiple designs, and has shipped to over 50 million PC and embedded systems customers.TrueTask USB is used by Microsoft as the USB stack for Windows 10 IoT Core for Raspberry Pi 2 and 3. A fully functional evaluation version is also available for Windows 10 ARM64 on the Raspberry Pi 3 through pi64.win.
What is a USB platform?
The notion of a software platform is familiar: it’s a design environment that allows code to be written that is subsequently unaffected by changes to the operating system, CPU, compiler, and so forth. In the embedded system world, Linux is a good example of a platform for application programs.
For reasons of efficiency, USB system code (the host and device stacks, the class and protocol drivers, and the management code) normally resides in the operating system kernel. Unfortunately, most operating systems that serve as application platforms do not serve as good system software platforms. In Linux, for example, the kernel APIs are not stable, and may change from kernel version to kernel version (2.6.35.7 may be different than 2.6.35.6, for example). Products based on embedded systems have similar differences between major versions. For a system vendor, this is very inconvenient, because multiple source versions must be maintained; bug fixes and system-specific adaptations cannot be automatically applied to any given environment, but must be scrutinized for correctness.
This is particularly a problem when it comes to USB host stacks. By its nature, USB is an open standard. No matter how well tested and supported a stack is, patches may be required to support a new and popular device that deviates from USB standards (but just happens to work with Windows or OS X). This presents problems. If the stack is from a commercial RTOS vendor, often you must update to the latest version of the RTOS to get all the corrections. However, if the stack is not designed to be a platform, you will have to modify your application code; and you may have to re-port the stack onto your platform. This may not be practical, because extensive testing is generally required.
If working with Linux, the problem can be even more difficult. Because of changes in kernel APIs, it is usually not practical to port the entire USB stack back to an earlier kernel version. Instead bug fixes must be identified, and then back ported. However, fixes may depend on other corrections made to the stack; so they may not work by themselves. Furthermore, fixes in the enumeration code may cause other devices to stop working.
How TrueTask USB provides a USB platform
TrueTask USB offers all the basic features one expects from an embedded USB host stack: extensive SoC support, small memory footprint, efficient run-time operation, and a variety of class drivers. TrueTask USB is different than a traditional embedded USB host stack, in that it’s based on a foundation of stable APIs. Stable APIs allow seamless reuse of your investment in code based on TrueTask USB. These APIs are designed portably, so that the C code using them is portable across CPUs, operating systems, and host/device controller register models. They are also designed to be stable over time, so that code written with one version of TrueTask USB will be reusable with subsequent versions. Furthermore, they’re internally stable as well. This means that a change, for example, in the host controller driver will not affect TrueTask USB code in any other layer; only minimal retesting is needed.
MCCI’s commitment to stable APIs protects our customers’ investments in USB software, and enables our customers to continue reusing their applications and class drivers from previous projects. Htc network & wireless cards driver download for windows. For example, customers who upgrade a product using TrueTask USB to a new SoC will be able to reuse their legacy USB software applications and USB class drivers seamlessly. This allows customers to maximize the return on their investment of development time, testing, and field experience with prior products.
How TrueTask USB enables stable APIs across so many platforms
MCCI has been creating stable APIs for USB for twenty years. Several distinctive design practices have resulted.
- We explicitly version API functions that are called by name. If a function changes, we write a new version, and express the old version in terms of the new version. Our library-oriented, one-function-per-file source base for API implementations means that the wrapper code for the older versions is only used if required.
- MCCI avoids conditional compiles in our C code. In addition to other benefits, this makes the important configuration and run-time parameters visible early in development.
- We prohibit use of OS header files except in the wrapper modules that bridge between TrueTask USB APIs and the local platform APIs. In addition to greatly simplifying compile-time configuration management, these practices force our code to depend on the inter-module APIs for managing all CPU, OS and hardware variations, rather than using “#if” and compile-time variables.
- We use macros to initialize API data structures, and then explicitly version those macros. This makes client source code insensitive to data structure order, naming, or layout.
- MCCI code is coded without static or global variables. This again makes certain design assumptions explicit that would otherwise be explicit, and forces us to make relationships between system-wide objects clear at design time.
MCCI is able to evolve APIs as the USB standards evolve; by maintaining the older, stable APIs, we isolate our customer’s legacy code from changes in the stack.
How TrueTask USB enables reuse of USB software investments
Customers switching from existing USB stack implementations to TrueTask USB can still reuse their existing software investment. TrueTask USB includes local operation system USB host stack emulations. These emulations are fast and highly compatible, allowing TrueTask USB to support “in-box” class drivers shipped with the local operating system or developed by our customers. Whatever USB applications customers have running on the existing USB host stack implementation will seamlessly work over the TrueTask USB host, and will be able to access the additional features provided by TrueTask USB: SuperSpeed support, composite device support, role switching, and so forth.
Embedded systems benefit from TrueTask USB’s Windows deployment
TrueTask USB includes a production-quality Windows stack emulation. This allows direct test and validation of new USB controller designs on Windows, with a minimum of effort, and allowing test with an enormous variety of class drivers and device applications. The TrueTask USB host controller driver (HCD) API is a platform API, and allows direct test of non-EHCI/xHCI architectures such as the Synopsys DesignWare OTG USB 2.0 core, using the full variety of Windows devices.
When developing an embedded system, you therefore can first test the system components on Windows. This exercises the HCD, the hub drivers, the enumeration logic. Customers can also code to our generic APIs, and test large portions of their applications on Windows. When the software is moved to the embedded system, any variations are systematic and easy to track down.
How TrueTask USB Host is optimized to support real-world USB devices
Other embedded USB host stacks implement class drivers according to the USB-IF specifications. Why does it so often happen that these embedded host stacks fail to support certain USB devices, despite the user’s claim “but it works with Windows”?
The answer is found in the gap between the class driver specifications of USB-IF and what real-world device manufacturers produce.
Simply put, other embedded USB host stacks implement class drivers by their interpretation of the USB-IF specification – while USB device makers test and verify against the Windows USB host stack. The result is a mismatch between device and host implementation.
It is no secret that consumer device makers with USB connectivity mostly target the PC market, and use standards only for reference. Product test consists of interop test with Windows and OS X. As a result, these devices work perfectly with Windows or OS X; but there is no real guarantee that they are in fact standard compliant, so there’s no guarantee that they will work with an embedded USB stack.
TrueTask USB is not just compatible with Windows; it is shipped in mass production as the USB host stack with multiple PC and laptop brands as the sole USB host stack on Windows. The USB enumeration logic, the handling of suspend/resume, the timing and sequencing of USB operations have all been tested and proven by customer experience to be compatible with what CE device makers test against. All this “USB business logic” is embedded in the portable portion of the TrueTask USB stack, so all users benefit from this experience.
Dual Role Host/Device Support
It is increasingly common to multiplex a single physical USB connector to operate it either as a host or device. To support this, TrueTask Dual-Role USB has complete support for dual-role USB Type C, dual-role USB 3.2/2.0, and USB 2.0 On The Go, combining the TrueTask USB host stack with the MCCI USB DataPump device stack.
