dfu-util

USB Device Firmware Upgrade (DFU) is an official USB device class specification of the USB Implementers Forum. It specifies a vendor and device independent way of updating the firmware of a USB device. The idea is to have only one vendor-independent firmware update tool as part of the operating system, which can then (given a particular firmware image) be downloaded into the device. In addition to firmware download, it also specifies firmware upload, i.e. loading the currently installed device firmware to the USB Host. The DFU specification can be found at: http://www.usb.org/developers/devclass_docs/usbdfu10.pdf
