I have three sub-generic USB programming cables for my Baofeng. Two of three operate in this way, where I have to try to program the (turned off) radio first, and then turn on the radio. I believe this is due to the ultra-crappiness of the cables.
The one cable that doesn't do this, I can program normally, and it operates like it should (does not open TX when plugging in the cable).
Luckily, we don't need to program our radios constantly. This is just a minor annoyance.
(chirp + osx + baofeng)

OK, after some more playing around, I think in my case the problem is indeed mechanical.
I have 2 cables. The one that came with the radio and a Baofeng branded one I bought when I couldn't get the first one to work with the Mac.
I now think the original issue was not having the right Prolific chip drivers, but as I then changed the cable as well, *that* became the problem.
Going back to my original cable, and it works every time. (Except after first plugging in - seems that until Chirp has tried to communicate the ports are in the wrong configuration, and it opens up the mic.)
So my - so far - way of working is:
Plug cable into USB Launch Chirp Try to download - this will fail Plug cable into radio (while it is off) and then turn radio on Now download (or upload, I guess - not tried yet) seems to work fine.
