I could not find the mouse acceleration in the configuration. Not sure if it's in the controls when you're in-game though.
I really need the accelleration, because I use the Logitech Cordless Trackman. This trackball is only 300dpi (as are all trackballs), but all games that have accelleration make it a lot faster.
I hope STO has the acceleration hidden somewhere...
PS... don't flame me on using a trackball. I use it because I have suffered from beginning RSI in the past. And after almost 15 years of using a trackball, I can't even play games anymore with a regular mouse. My old guild-mates from several other games were impressed by the PvP/PvE things I could do with the trackball - it just takes practice
