You didn't indicate version or OS, so I will guess here. In your
hotplug scripts directory (/lib/udev on Ubuntu), you should find one or
more scripts with "gpsd" in the file names. Remove them or move them

Not directly. But a bit of scripting using gpsdctl (assuming a recent
version of gpsd, say since June, 2011) and gpsdlogger should give you
a way to do that. See the gpsd hotplug script(s) for ideas.

Recent versions with gpsdctl are much easier to work with. If you
aren't using a version with gpsdctl, consider upgrading to one.

I have no idea what your application does, so this is a guess. Perhaps
have your application test the devices, and have it launch gpsd on the
appropriate one.
