There are three methods for you to fix this issue. You may not have to try them all; just work your way down the list until you find the one that works for you.
TIP : If both of your usb keyboard and mouse stop working, use the touchpad, a PS2 mouse or a PS2 keyboard to perform the following procedure. Follow these steps: 1. If prompted for confirmation, click the box next to Delete the driver software for this device if you see this , and click OK button.
To fix the problem, you can try updating the Chipset drivers. Chipset drivers are responsible for controlling communication between various components in your system like USB devices, which includes the USB drivers. To download the correct drivers, you need to know the PC model and the operating system version.
Usually, you can get the PC model on the PC. To get operating system version, click here for the instructions. Driver Easy will automatically recognize your system and find the correct drivers for it. But with the Pro version it takes just 2 clicks and you get full support and a day money back guarantee :. The EnumLogEntry routine makes a log entry. UcmConnectorCreate Creates a connector object.
UcmTcpciPortControllerStart Indicates to the UcmTcpciCx class extension that the client driver is now ready to service hardware requests for the port controller.
UcmUcsiPpmStart Instructs the class extension to start sending requests to the client driver. UcmUcsiPpmStop Instructs the class extension to stop sending requests to the client driver.
The client driver calls this function before calling UcxEndpointCreate method to create an endpoint and register its callback functions with UCX. UcxControllerCreate Creates a host controller object.
UcxControllerSetIdStrings Updates the identifier strings of a controller after the controller has been initialized. UcxStaticStreamsCreate Creates a static streams object. This applies to virtual USB 3. UdecxUsbEndpointInitSetEndpointAddress Sets the address of the endpoint in the initialization parameters of the simple endpoint to create. UfxDeviceCreate Creates a UFX device object, registers event callback routines, and specifies capabilities specific to the controller. UfxEndpointCreate Creates an endpoint object.
UrsDeviceInitialize Initializes a framework device object to support operations related to a USB dual-role controller and registers the relevant event callback functions with the USB dual-role controller class extension.
UrsDeviceInitInitialize Learn how this function initializes device initialization operations when the Plug and Play PnP manager reports the existence of a device. The request opens streams associated with the specified bulk endpoint.
The routine registers the client driver with the underlying USB driver stack. The properties are static information that do not change during the lifecycle of a connector.
Unlike connector properties, state information is dynamic, which can change at runtime. Properties are static information that do not change during the lifecycle of a hub. For information about these members, see the Power Delivery specification.
See Table See Bit in Table See Section 3. For information about the structure members, see Universal Serial Bus Revision 3. SuperSpeed Hub Descriptor. For more information, see section 9. 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. Windows defines MS OS descriptors that allows better enumeration when connected to system running Windows operating system.
Windows provides in-box device class drivers for many USB-IF approved device classes, audio, mass storage, and so on. Windows provides Winusb. Parent driver for USB devices with multiple functions. Usbccgp creates physical device objects PDOs for each of those functions. 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.
A useful resource for USB client driver developers and USB hardware designers understand the driver stack implementation, resolve common issues, and explain how to use tools for gathering traces and log files. Discussion list managed by OSR Online for kernel-mode driver developers. Miscellaneous resources based on frequently asked questions from developers who are new to developing USB devices and drivers that work with Windows operating systems.
They provide automated testing that can be used during the development cycle of USB controllers, devices and systems, especially stress testing. If you are new to USB driver development. The kit is the most suitable to study USB samples included in this documentation set. Introduces you to USB driver development. Provides information about choosing the most appropriate model for providing a USB driver for your device.
