Does anybody know how to make it so I can plug my GPS in and not get into an infinite loop of Parallels asking me if I want to attach it to my guest OS, and then telling me that somebody else already has it in use? I've also tried telling it not to attach it, and then using the device menu to attach it, same result. I've also edited the configuration to attach USB devices to the Guest OS instead of asking (as suggested in another thread in this forum), but that didn't help. I've verified that other USB devices like thumb drives work fine, and also that the GPS works if I boot into Boot Camp. One strange thing: The GPS doesn't show up in the System Profiler.
