Code looks basically correct - I don’t use quite that method, I set up notifications so I get dynamic adds and deletes but the dictionary I use it set up the same way, just passed to a different function. I can’t really paste any more code because it’s quite an edifice of classes I set up at the time to handle generic IOKit stuff and the matching code is sprayed around the place. Couple of things. What’s kernResult? Is serialPortIter actually getting set to anything (don’t recall whether the IOIteratorNext() checks for nil pointers, I think it may). If you don’t add keys to the dictionary at all do you still get stuff, how about using a different class than BSD just to see if you can get some matches for something. Last idea - get your own master port with IOMasterPort just to see if that helps despite the documentation telling you to use the constant. If nothing else the error returns from doing that might tell you if you have problems. > On 6 Jun 2015, at 09:14, Carl Hoefs <[email protected] > <mailto:[email protected]>> wrote: > > Thanks for the suggestion.
