Netarc,

I just showed your post to one of our engineers. He echoed the question we all asked (when shown this post): Are you using a USB to Serial adaptor? Which one?

The message you are seeing indicates a hardware conflict and the most likely answer is your USB adaptor. We've had tremendous success with the Belkin unit and I'm sure other posters here can make other suggestions for brands as well.

I asked around and no one else has seen this, although a likely solution is the adaptor - so can you let us know which one you use and we'll make sure others don't use that one?
