Agree, I've seen the same with CP200's here. Here's my sequence:
1. Plug the USB cable into the PC.
2. Fire up the CPS.
3. Turn on the radio.
4. Plug the cable into the radio.
I've also found that if you click Edit, then Preferences, and then set your Comm Port when you first fire up the CPS, you may avoid this error. Don't click Cancel, click OK. For some reason, sometimes the CPS knows your comm port and sometimes it needs to be pointed at it. It may sound trivial, but it prevents a lot of frustration.
