Hi,

I am a Windows/C/C++ programmer who is trying write some code to find
and list all usb modems using Xcode 2.5.
Any help would be greatly appreciated.

Thanks.

Additional info:
All my usb modems appear in the terminal with names that begin with
tty.usbmodem in the /dev folder.

Is there a MAC equivalent of findfirst/findnext of "dev/
tty.usbmodem*"?

Thanks again.

Is there a reason you do not use a newer version?

That may be the case with all your USB modems, but how can you be sure
that that is the case for all USB modems?

You probably want to go a different route, for instance by calling
system_profiler (check the GUI app System Profiler first. If it provides
the info you need, system_profiler should be able to provide it, too) or
by using I/O Kit, iterating over all USB devices, and checking which
ones are modems. See

The code there does not restrict itself to USB modems, but you could
certainly add that kind of filtering of the result list if you need to.
