Actually, turning on Enhance Pointer Precision in CP will mess up your cursor movement with acceleration. I suggest you to disable it and apply MarkC Windows 7 Mouse Acceleration Fix if you're using Win7 since it is questionable if disabling precision will completely remove acceleration in Win7. I also suggest you to use 6/11 pointer speed in CP since 11/11 will cause a lot of skipping.
About precision in osu! itself, dunno what it really does but I tend to turn it off.
Anyhow, mine's Logitech G400, 800dpi, 6/11 w/ precision off in CP, 1.0 w/ precision off in osu!
Just an fyi to anyone who thought G400 had prediction, mine's newer one without prediction and its sensor is Avago 3095 instead of Avago 3080E (which the older one used and had prediction).
