USB Audio 2.0 Class Driver for Windows 10 and Windows 11

Features      Supported Platforms      Demo      Prices      


Thesycon’s USB audio class driver TUSBAudio targets USB audio devices for professional and semi-professional use and highest quality audiophile HiFi systems. The driver supports devices which are compliant to the USB Audio 2.0 or USB Audio 1.0 device class specification. The driver provides an ASIO 2.3.1 compliant software interface and integrates with Windows as a standard WDM/DirectX compatible sound device. If the device provides MIDI features the driver exposes standard Windows MIDI ports.

To meet professional audio requirements, the audio class driver is optimized for low latency and low CPU load. Buffer depths can be adjusted by the user to optimize settings for a given computer. The driver implements a transparent (bit-perfect) playback and recording data path.

Device and Firmware Requirements

The USB Audio 2.0 Class Driver for Windows implements the USB Audio 2.0 and 1.0 device class specification and is independent of the specific silicon and firmware solution used in a given device. As long as the hardware and firmware implement the descriptors, endpoints and requests defined in the class specification the driver should work. However, there are some requirements and assumptions as listed below.

Current Version: 5.68

Security Advisory (CVE-2024-25376)

An Insecure Permission vulnerability in the MSI-based driver installer has been reported by Julian Horoszkiewicz from the Eviden Red Team. The MSI installer before v5.68 allows a local attacker to execute arbitrary code via the msiexec.exe repair mode. A local user can trigger msiexec in repair mode (/fa flag) on the MSI package present in C:\Windows\Installer. In result, a copy of tlsetupfx.exe executable is executed with SYSTEM privileges, from the local %TEMP% directory, creating a race condition giving the regular user an opportunity to switch executable files (e.g. DLLs) and get their own code executed as SYSTEM.


All TUSBAudio driver installers after v5.40.0 and before v5.68.0 are affected.


For more information about this vulnerability, see also CVE-2024-25376.


Thesycon has fixed the vulnerability in v5.68.0 and provides updates for all affected driver packages. Thesycon strongly encourages customers to update any released driver packages.

USB Vendor and Product ID

For each USB device model an official USB vendor ID (VID) is required. Vendor IDs must be unique and will be assigned by the USB Implementers Forum ( Registration fees will be charged.


Thesycon owns a USB vendor ID and provides a subset of product IDs (PID) to licensees of Thesycon drivers.
