TL-USBDFU Solution for Windows and macOS
TL-USBDFU is a host-side, cross-platform, customizable software solution that implements firmware upgrade via USB. It works with devices that are compliant to the USB device class specification for Device Firmware Upgrade (DFU) version 1.1. The solution is available for Windows and macOS.
The overall software architecture is shown right.
The core component is a dynamic link library which provides a cross-platform implementation of the DFU protocol. The library exposes a unified, C-style API which behaves in the same way on all supported platforms. Based on this API custom applications or scripts can be built which work across all platforms. A customizable application with graphical user interface and a command line based utility is included.
- Windows 11 (64-bit and arm64)
- Windows 10 (32-bit and 64-bit)
- Windows Server 2019 64-bit
- Windows Server 2022 64-bit
- macOS 13 Ventura (Apple M1 and Intel)
- macOS 12 Monterey (Apple M1 and Intel)
- macOS 11 Big Sur (Apple M1 and Intel)
TL-USBDFU Key Features
- Works with DFU 1.1 compliant devices
- Supports USB 2.0 full speed and high speed, and USB 3.0/3.1/3.2 super speed or higher
- C-Style, script-friendly, cross-platform programming interface
- SDK with sample code available
- Driver-less operation on Windows 10, Windows 11, macOS
GUI Utility for Windows and macOS
The TL-USBDFU solution includes an application with multi-language graphical user interface for Windows and macOS. The application can be configured through an external .xml file. Firmware images can be bundled with the application, and a matching image will be selected automatically for the connected USB device. The user interface supports multiple languages. English and German translations are included.
DFU Application Key Features
- Application behavior is customizable through external .xml file using common syntax and semantics for Windows and macOS
- Firmware image files can be bundled with the application; the image will be selected depending on the detected device type
- User-friendly and foolproof firmware update for a set of different device models (device family) can be delivered as one single software package
- Additional user-interface languages can be implemented through external text files with unified format for Windows and macOS; only one translation effort needed to support both platforms
- Branding supported: application name, icon and title can be customized

Example Scenarios
Some examples where the TL-USBDFU solution is useful are given below.
- USB Audio Class 2.0 or Audio/MIDI 1.0 device which works with Windows and macOS built-in class drivers but DFU support is missing
- USB Audio Class 2.0 and/or MIDI device (e.g. XMOS based) which works with Thesycon’s TUSBAudio driver on Windows but DFU support is missing on macOS
- USB device which works with built-in class drivers (e.g. CDC/ACM, Mass Storage) but requires firmware update support as well
- USB device which requires a uniform DFU API under Windows to implement script-based firmware programming during development and in the factory
