Stephen Fry and DVD Jon Back USB Sniffer Project
An anonymous reader writes "bushing and pytey of the iPhone DevTeam and Team Twiizers have created a Kickstarter project to fund the build of an open-source/open-hardware high-speed USB protocol analyzer. The board features a high-speed USB 2.0 sniffer that will help with the reverse engineering of proprietary USB hardware. The project has gained the backing of two high-profile individuals: Jon Lech Johansen (DVD Jon), and actor and comedian Stephen Fry."
Stephen Fry also did a video for the GNU project's 25th birthday:

He's not just a comedian though is he? Most actresses know less about foreign policy than Sarah Palin, whereas Stephen Fry knows a lot about open-ness, DRM and the importance of being able to play a DVD on the OS of your choice. Should we ignore anything Brian May has to say on the subject of Astrophysics because he's "just a musician"?

He's Brian Cox, OBE.
Or he's Brian May-of Queen, with a PHD in astrophysics from Imperial College... http://en.wikipedia.org/wiki/Brian_May
Two main reasons: Embedded device peripherals, and USB device development. Sometimes you don't have access to the OS running on the host to set up a sniffer (game consoles, some smartphones, and similar). And sometimes you need to debug a USB device that you're developing, and software USB sniffers don't provide the kind of detail needed to do that effectively (some errors are only evident when you watch the stuff on the wire, not the high-level requests).
Also, software sniffers are imperfect. I've had issues with them. A physical hardware device is completely transparent and can work without either side noticing anything. Sure, you can make do with a software sniffer sometimes, but that doesn't mean there's no point to a hardware version.
And since this is open, it can be repurposed for other uses. For example, you could use only the device port, and turn it into a kind of usb device-to-device bridge that lets your computer impersonate a USB device. That is currently not possible except on embedded systems with USB device controllers, and those have limitations. You could also use it as a pretty good logic analyzer, given proper firmware.
