Exar Usb Devices Driver Win 7

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

Generally USB drivers are supplied as part of the Windows 10 Operating System, sometimes, your PC manufacturer will supply specific USB hub drivers. Open Device Manager (accessible by right clicking your Start Button) At the bottom of the hardware section list is the USB devices section, expand that. These drivers are not needed for newer Garmin devices that use a USB mass storage or Media Transfer Protocol (MTP) interface. These devices (which include the nuvi and zumo series) use drivers that are included with Microsoft Windows. The drivers for Garmin Mode devices are included with the latest versions of Garmin Express and Garmin WebUpdater.

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.

Usb

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.

Method 3
