This article helps to fix an issue in which Windows 10 doesn't install specific drivers for USB audio devices on the first connection.

Original product version: Windows 10, version 1703
Original KB number: 4021854

Symptom

When you connect a USB audio device to a Windows 10 Version 1703-based computer the first time, the operating system detects the device but loads the standard USB audio 2.0 driver (usbaudio2.sys) instead of the specific device driver.

Cause

This issue occurs because the USB audio 2.0 driver (usbaudio2.sys) isn't classified as a generic driver in Windows 10 Version 1703. Therefore, the system assumes that a compatible, nongeneric driver is installed for the device even though the driver is generic.

This issue also causes Windows 10 Version 1703 to postpone the search for other compatible drivers through Windows Update that typically occurs immediately after you install a new device.

Resolution

To fix this issue, use one of the following methods.

Method 1

To resolve this issue, install update 4022716.

Method 2

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.

Method 3

If the device is not yet connected, first install the device-specific driver, such as by using the appropriate installer. After the device-specific driver is installed, Windows 10 will select that driver instead of the standard USB audio 2.0 driver when you first connect the device.

Note

See the device manufacturer's user guide for specific instructions about how to install the driver.

Method 4
