LibUsbDfu is a C# USB DFU firmware upgrade utility using LibUsbDotNet,
DeviceProgramming and Mono.Options.
The program performs the entire DFU upgrade procedure - booting to update mode, downloading the firmware and manifesting it - by a single command.
It accepts .hex, .s19 and .dfu image file formats as input.
LibUsbDfu.Cli -d 483:5740 -v 1.12 -i "newfw.hex"
Note: The USB VID:PID and version are overwritten from the .dfu file if that format is provided.
Unlike HID or MSC, the USB DFU class isn't recognized natively by today's OSes, therefore the interface driver must be created and distributed for each device. LibUsbDotNet is used as an underlying USB device interface, as it provides the most direct USB access on the widest platform range.
