USB man-in-the-middle adapter - Hack a Day

The module works as a pass through, providing access to data and power lines for a USB device. [BadWolf] built it in order to sniff out communications between peripherals and the Universal Serial Bus. For now it just provides access to the different signals, but we think there’s quite a bit of usefulness in that. First off, the power rail is mapped out to a jumper, making it dead simple to monitor the voltage stability or patch in a multimeter to get feedback on current consumption. But you can also see in the foreground that a pin socket makes it easy to tap into the board using jumper wires. We think it would be a great breadboard adapter for USB work that would continue being useful after you’ve populated your first PCB for the prototype.

[BadWolf] has other plans in store for it though. He wants to intercept and decipher the communications happening on the data lines. In the video after the break he mentions the possibility of using a Bus Pirate for this (we have our doubts about that) but plans to start his testing with an STM32 discovery kit. We can’t wait to see what he comes up with.
