Before you begin

Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:

Update the device driver

The package provides the installation files for Microsoft MTP Device Driver version 3.0.1504.0. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version.

In the search box on the taskbar, enter device manager, then select Device Manager.
Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update.
Select Search automatically for updated driver software.
Select Update Driver.
If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

Reinstall the device driver

In the search box on the taskbar, enter device manager, then select Device Manager.
Right-click (or press and hold) the name of the device, and select Uninstall.
Restart your PC.
Windows will attempt to reinstall the driver.
Usb ports driver download. Update the device driver In the search box on the taskbar, enter device manager, then select Device Manager. Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update. Select Search automatically for updated driver software. If the device-specific driver is distributed through Windows Update, you can manually update the driver by using Device Manager. For more information about how to do this, see update drivers in Windows 10. If the device is not yet connected, first install the device-specific driver, such as by using the appropriate installer. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port.

[Applies to KMDF and UMDF]

A driver's EvtDevicePrepareHardware event callback function performs any operations that are needed to make a device accessible to the driver.

Syntax

Parameters

Device

[in]A handle to a framework device object.

ResourcesRaw

[in]A handle to a framework resource-list object that identifies the raw hardware resources that the Plug and Play manager has assigned to the device.

ResourcesTranslated

[in]A handle to a framework resource-list object that identifies the translated hardware resources that the Plug and Play manager has assigned to the device.

Return value

If the EvtDevicePrepareHardware callback function encounters no errors, it must return STATUS_SUCCESS or another status value for which NT_SUCCESS(status) equals TRUE. Otherwise, it must return a status value for which NT_SUCCESS(status) equals FALSE. Do not return STATUS_NOT_SUPPORTED.

If NT_SUCCESS(status) equals FALSE, the framework calls the driver's EvtDeviceReleaseHardware callback function.

For more information about this callback function's return values, see Reporting Device Failures.

Remarks

To register an EvtDevicePrepareHardware callback function, a driver must call WdfDeviceInitSetPnpPowerEventCallbacks.

If the driver has registered an EvtDevicePrepareHardware callback function for a device, the framework calls the function after the Plug and Play manager has assigned hardware resources to the device and after the device has entered its uninitialized D0 state. (The Plug and Play manager always starts a parent device before it starts that device's child devices.)

The framework calls the driver's EvtDevicePrepareHardware callback function before calling the driver's EvtDeviceD0Entry callback function.

The EvtDevicePrepareHardware callback function accesses the device's raw and translated hardware resources by using the ResourcesRaw and ResourcesTranslated handles that it receives. The callback function can call WdfCmResourceListGetCount and WdfCmResourceListGetDescriptor to traverse the resource lists. This callback function cannot modify the resource lists.

For more information about resource lists and the order in which the resources appear, see raw and translated hardware resources.

Typically, your driver's EvtDevicePrepareHardware callback function does the following, if necessary:

Maps physical memory addresses to virtual addresses so the driver can access memory that is assigned to the device
Determines the device's revision number
Configures USB devices
Obtains driver-defined interfaces from other drivers

Optionally, your driver's EvtDevicePrepareHardware callback function might queue a work item to complete any other time-intensive configuration tasks. Using a work item for such operations can help ensure that your device's start up time does not increase the system boot time. For more information, see Using Framework Work Items.

Typically, all other hardware initialization operations, including loading firmware, should take place each time that the device enters its working (D0) state and should therefore take place in the driver's EvtDeviceD0Entry callback function.

The ResourcesRaw and ResourcesTranslated handles that the EvtDevicePrepareHardware callback function receives remain valid until the driver's EvtDeviceReleaseHardware callback function returns.
