Universal Serial Bus (USB) provides an expandable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices. USB devices include keyboards, mice, joysticks, printers, scanners, storage devices, modems, video conferencing cameras, and more.
Windows operating systems include native support for USB host controllers, hubs, and devices and systems that comply with the official USB specification. Windows also provides programming interfaces that you can use to develop device drivers and applications that communicate with a USB device.
If you're developing an xHCI host controller that isn't compliant with the specification or developing a custom non-xHCI hardware (such as a virtual host controller), you can write a host controller driver that communicates with UCX. For example, consider a wireless dock that supports USB devices. The PC communicates with USB devices through the wireless dock by using USB over TCP as a transport.
You can develop a controller driver that handles all USB data transfers and commands sent by the host to the device. This driver communicates with the Microsoft-provided USB function controller extension (UFX).
Windows 10 introduces support for the new USB connector: USB Type-C. You can write a driver for the connector that communicates with the Microsoft-provided class extension module: UcmCx to handle scenarios related to Type-C connectors such as, which ports support Type-C, which ports support power delivery.
USB Dual Role controllers are now supported in Windows 10. Windows includes in-box client drivers for ChipIdea and Synopsis controllers. For other controllers, Microsoft provides a set of programming interfaces that allow the dual-role class extension (UrsCx) and its client driver to communicate with each other to handle the role-switching capability of a dual-role controller.
You can develop an emulated Universal Serial Bus (USB) host controller driver and a connected virtual USB device. Both components are combined into a single KMDF driver that communicates with the Microsoft-provided USB device emulation class extension (UdeCx).
Talk to USB devices, start to finish: Provides step-by-step instructions about implementing USB features in a UWP app. To write such an app for a USB device, you need Visual Studio and Microsoft Windows Software Development Kit (SDK).
Get information about the tools that you can use to test your USB hardware or software, capture traces of operations and other system events, and observe how the USB driver stack responds to a request sent by a client driver or an application.
Read an overview of tests in the Hardware Certification Kit that enable hardware vendors and device manufacturers to prepare their USB devices and host controllers for Windows Hardware Certification submission.
Microsoft Windows USB Core Team Blog: Check out posts written by the Microsoft USB Team. The blog focuses on the Windows USB driver stack that works with various USB Host controllers and USB hubs found in Windows PC. A useful resource for USB client driver developers and USB hardware designers to understand the driver stack implementation, resolve common issues, and explain how to use tools for gathering traces and log files.
MUTT devices: MUTT and SuperMUTT devices and the accompanying software package are integrated into the HCK suite of USB tests. They provide automated testing that can be used during the development cycle of USB controllers, devices and systems, especially stress testing.

USB host-side drivers in Windows: Provides an overview of the Universal Serial Bus (USB) driver stack architecture. Microsoft provides a core stack of drivers that interoperate with devices that are connected to EHCI and xHCI controllers.
USB-IF device class drivers: Lists the Microsoft-provided drivers for the supported USB device classes. Windows provides in-box device class drivers for many USB-IF approved device classes, audio, mass storage, and so on.
This reference section describes the driver programming interfaces that are included in the Windows Driver Kit (WDK). The programming interfaces are used for developing drivers that interact with USB devices, host controllers, connectors. These include export functions that the drivers can call, callback routines that the driver can implement, I/O requests that the driver can send to the Microsoft-provided USB driver stack, and various data structures that are used in those requests.
A Windows Driver Model (WDM)-based USB client driver can call functions to communicate with the Microsoft-provided USB driver stack. These functions are defined in Usbdlib.h and the client driver requires the Usbdex.lib library. The library gets loaded and statically linked to the client driver module when it is built. A client driver that calls these routines can run on Windows Vista and later versions of Windows.
A USB driver for a dual-role controller can behave as a host controller or a function controller depending on the hardware to which it is connected. These controllers are common on mobile devices and allow for connections to PCs, as well as USB peripherals like keyboards and mice. A mobile device can behave as a peripheral when it is connected to a PC, allowing you to transfer files between your PC and the mobile device. In that scenario, the controller on the device operates in the function role. Conversely, the controller can operate in the host role when connected to USB peripherals like storage drives, keyboard, mice.
One of the main responsibilities of a driver for a dual-role controller is to switch between those two roles, tearing down the previous role's device node and loading the device node for the new role. When writing the driver, use the WDF class extension-client driver model. For more information about the WDF class extension-client driver model, see Ursdevice.h.
The driver pair loads as the FDO in the host controller device stack. The UDE client driver communicates with Udecx by using a set of methods and event callback functions to handle device requests and notify the class extension about various events.
A USB function class driver implements the functionality of a specific interface (or group of interfaces) on the USB device. The class driver handle requests issued by user mode services, or it can forwards requests to USB function class extension (UFX) and its function client driver. Certain class drivers are included in Windows, such as MTP and IpOverUsb. Windows also provides a generic kernel-mode class driver, Generic USBFN (GenericUSBFn.sys). If a particular interface or functionality is not provided by a system-supplied driver, you might need write a function class driver. The class driver may be implemented as a kernel-mode driver by using Windows Driver Frameworks (WDF). Alternatively, you may implement it as a user-mode service. In that case, your class driver must be paired with the system-supplied class driver, Generic USBFN. For example, the MTP class driver runs as a user-mode service that transferring files to and from the device.
The USB function client driver is responsible for implementing a function controller-specific operations. The client driver communicates with the USB function class extension (UFX) module to handle endpoint data transfers, USB device state changes (reset, suspend, resume), attach/detach detection, port/charger detection. The client driver is also responsible for handling power management, and PnP events.
Write a filter driver that supports detection of chargers, if the function controller uses the in-box Synopsys and ChipIdea drivers. If you are writing a client driver for a proprietary function controller, charger/attach detection is integrated in the client driver by implementing EVT_UFX_DEVICE_PROPRIETARY_CHARGER_SET_PROPERTY, EVT_UFX_DEVICE_PROPRIETARY_CHARGER_RESET, and EVT_UFX_DEVICE_DETECT_PROPRIETARY_CHARGER.
The USB host controller extension is a system-supplied extension to the Kernel-Mode Driver Framework (KMDF). Within the Microsoft USB Driver Stack Architecture, UCX provides functionality to assist a host controller client driver in managing a USB host controller device. The client driver handles hardware operations and events, power management, and PnP events. UCX serves as an abstracted interface to the rest of the Microsoft USB 3.0 stack, queues requests to the client driver, and performs other tasks.
If you are developing an xHCI host controller that is not compliant with the specification or developing a custom non-xHCI hardware (such as a virtual host controller), you can write a host controller driver that communicates with the UCX class extension.
If the rest of your PC is operating correctly, I would install an expansion USB card. When the computer boots up, it should install drivers for common chipset with no problem. Though you mentioned logging in, I'm under the impression that you should still get basic USB function for keyboard and mouse.
Failing that, if you have a USB 3.0 header, you can plug a USB 2.0 device in USB 3.0 socket and the USB 3.0 and USB 2.0 run off different controllers so should hopefully give you enough love to login and restore your old drivers.
Since USB is recognized when you plug it in, trying unplugging both mouse and keyboard. Turn off computer. Wait one minute, then turn on computer. Wait till everything is done loading, and plug both in again. Windows should recognize the usb connections and reinstall usb drivers.
Following method worked for me and maybe work for people with the same problem too. Restart your computer and press F8 to see 'Advanced Boot Options' and choose 'Last known good configuration'. I have windows 7 and I don't know if you should use another key to see that page in other windows versions. Also after repairing your computer, don't forget about enabling 'System Restore'.
