This was the only problem I have ever had with mine.
I got home from my 2,000 kj commute and went to DL my ride data. CPU said "HOST" but neither Training Peaks nor PowerAgent would recognize it. I took it off the USB cradle several times and made sure I heard a good click. I then realized "hey the CPU displays "HOST" even when not in the cradle. I pushed mode and select and the screen wouldn't change. Just for kicks I docked it on the bike and gave the wheel a spin and still nothing. So I googled and found this thread. This post in particular caught my attention. When I removed and reinstalled the battery on the CPU I lost fours of ride data.
So beware....
