András Veres-Szentkirályi is part of the H.A.C.K. hackerspace in Hungary. They acquired an affordable, slightly used UNI-T UT2025B digital storage oscilloscope. He wondered what useful information could be gained from sniffing the USB port using Wireshark on a Linux box.
I managed to reverse engineer the USB connection of the Chinese digital storage oscilloscope our hackerspace got to transfer screenshots. The resulting software is not only more portable and free as in both senses, but can take 16 color screenshots (as it can be seen on the bottom of the blog post), while the LCD is monochrome and the original software downgrades the transmitted image too on purpose.
Here’s the link to Andras’ complete post containing more screenshots and links to the resulting open source code.
