So when playing with the demos of the ps3, I found that sometimes the program *start_rpi* failed to start and saying *CM 730 is in use*.

I guess it is because I ran the motion editor (rme) before running the ps3 demo, so I restarted the RPI, then ps3 demo works. Is my guess right? Any easier way to make it work without restarting the PC?
