Set your camera NOT to go to sleep.
Ha! Well, I tried to go back to edit this post to add a couple things, your answer being one of them, but it wouldn't let me edit.
That is something I was hoping to not have to do, as it's obviously a battery sucker and I was hoping not to have to buy an AC adapter and keep it plugged in and on all day long. That just doesn't seem like it's healthy for the camera, but I may be wrong.
I agree that Adobe needs to FIX the intermittent problems with tethering and also import. I have NO problem with tethering or importing using Apple Image Capture so Adobe should be able to get it right. I'm not sure how much power draw there is having your camera not go to sleep but it shouldn't be unhealthy for the camera if it is not in live view mode. Good cameras are pretty robust.
