Abstract
Embodiments of the invention provide a computer-implemented method for updating firmware of a Universal Serial Bus (USB) device. The USB device is configured to execute one or more applications of the USB device in a normal mode of operation of the USB device. The USB device includes a device descriptor indicative of one or more configuration descriptors, wherein a configuration descriptor is indicative of endpoints for data and command exchange. The device descriptor can be modified by adding a predefined bootloader configuration descriptor to the configurations descriptors for updating the firmware.
