Re: USB to Serial drivers for Mac OS X




I have worked with USB->serial devices since MacOSX beta days. Keyspan is the only manufacturer to provide reliable (as they get on mac) USB2Serial product line. I used their drivers from within C and Java, and they have been working fine for years.
Have to buy their hardware though.

Assuming you are looking for a plain old driver for your USB<- >Serial device check out the following. Generally people seem to have either the KeySpan connector like Scott said (which provides drivers) or they have this one:

Which has drivers here:

Which has a problem functioning correctly until you follow the instructions here:

There a definitely a number of quirks programming for the converters. You have to touch hardware a bit more. Sounds like some people on the list have run into some of these issues. You may want to look at a tutorial here:

Well, I bought one of those several years ago and I wouldn't
recommend it to anyone. I must have spent a month trying to get the
stupid thing to do anything at all before I saw the light and threw
it away. It would work for about two minutes, then you'd spend two
days trying to get it to work again. It had the most horrible-looking
and incomprehensible software I've seen looking like a DOS program
ported to the Mac (it made Epson scanner software look good). It
crashed the machine if you stupidly plugged it into a different USB
port from the last time you plugged it in unless you first delete its
preferences file. Keyspan never replied to any of the emails I sent
them and they'll never see another penny of my money ever again. Now
look what you've done: I'm all worked up again now. Where are my pills?


Of course, your mileage may vary :-)
