Thanks Karin, nice site and all. That or perhaps even their Aardvark http://www.totalphase.com/products/aardvark_i2cspi/ might do the job, if there's any chance of their linux software working, or being made to, and then if it works with our usb (gulp?). The xml scripting looks interesting at first glance. Aardvark only snoops up to 125kHz but looks good for master or slave, and may be the only one to work with USB 1.1 ports, ie both my laptops. Grabbed everything in sight, so have days of reading ahead. If the code and hardware is up to the quality of the docs, it looks like a winner at those prices. Lots of other good links from there too. cheers, Ian
