In usb boot mode distro boot should select usb device as primary boot device instead of usb host. So make usb dfu as primary boot device. But do not list it in boot_targets as fallback option because it is not classic mode for booting. Using 60s timeout by default should be enough time for dfu-utils to start transaction. In case none needs this please change timeout value in the command or disable CONFIG_DFU_TIMEOUT.
