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.
