A diode could fix that. The current should go from usb to power jack but not in the other direction.

Is there a way to prevent unmounting cards when you plug usb cable ? (by software configuration)
Yes, this is definitely solvable. Quick and dirty way is to edit
/usr/sbin/osso-mmc-umount.sh to return error. Just put 'false' command somewhere in the beginning. That would of course kill the usb storage feature altogether. It also shows error dialog. As another solution you could open some file from memory card (video? song?) before plugging in power. Same dialog should appear and card should be still usable after that.
