Thanks for the feedback everyone. TBH, I bought the adapter and three thermometers sight-unseen on eBay, not even knowing how I was going to make use of them in Linux. I was pleased to get them working.
@Gregg: Yep, the FTDI adapters are very widespread alright. I think I'm having some problems with their Mac OS X driver in another application though. @Paul: Can you elaborate on the electrical properties thing? Is it a feature of the DS2480B?
