Some microcontrollers I've been working with, that had USB capability also supported DFU- flashing new firmware via USB.
I have also resurrected a write-broken flash drive, by re-flashing it's firmware (a tool for which was provided by microcontroller vendor, which I found out by looking at VID/PID values and googling them).
- jessaustin 13y agoOh definitely it's possible for many microcontrollers. DFU is very handy during development. I was just reacting to this statement: Nothing is stopping a compromised host system from flashing the microcontroller on the USB stick to make it lie to you. Nothing, that is, except possibly a complete absence of such a facility! It depends on the microcontroller and how it has been wired into the USB device.
