Can I connect my APM 2.5 to the computer using the USB-cable and at the same time connect my 3S battery to the 3DR Power Module (connected to the APM) without damaging anything?
I read somewhere (without much motivation) that it could damage the board. Suspect that it will be ok if the current from the power module isn't to high? I saw a table somewhere on the http://copter.ardupilot.com/wiki/ but can't find it now of course.
The reason for asking is that I want to run "compassmot". The instructions doesn't include any warning about this however.
If it can be a problem, is this valid alternatives?
1. Run compassmot using the wireless telemetry module?
2. Create a custom USB-cable without the power pins attached?
Thanks!

No problem at all. That's how you normally do compassmot. I'm not even sure if you CAN run compassmot using the wireless telemetry.
Not on the APM 2.6 it will die!!!
Mine did.
But I had an SBEC feeding the RX and RX connected to the APM 2.6.
Seems it is different to the APM 2.5 because I have seen a video on YouTube that shows exactly what I did and it worked fine??
