Emulating USB DFU to Capture Firmware
- mmastrac 11y agoWhile this is a pretty cool hack, if you are really serious about hacking USB devices there are lots of USB sniffers that are cheap and will be able to capture the entire DFU transaction and doesn't require guessing at emulating host functions. I personally like this one, but it's a little more expensive at ~$700 and only does up to USB2: http://www.internationaltestinstruments.com/products/97-1480a-usb-20-protocol-analyzer.aspx http://www.internationaltestinstruments.com/products/97-1480... I haven't looked into open-source solutions myself, but http://openvizsla.org/ http://openvizsla.org/ looks like a potential candidate too.
