System is PS2........ Controler is PS3 usb.....

Your controler is either low on battery charge, or it needs to re-sync with the system.
If you still have the message while it is plugged in, then either the plug is worn, cable has worn out, or it is the wrong kind of USB cable. Some cables do not have a data connection and although they may work to charge the controler, they will not work to sync the controler to the system. Make sure nobody switched your cable for the kind used only to charge cellphones, as USB charger cables do not usually have the data pins enabled.
If it is the correct cable and works for other PS3 controlers, then it could be a worn socket on your controler and no way to really fix except to buy a new controler.
Another, more rare possibility is something wrong with the controler internally, which can sometimes be fixed by using a small pin, like a safety pin and pressing it into the tiny "reset" hole on the bottom of the controler, while it is plugged in to the USB cable and PS3., then pressing the PS3 button on the controler to make sure it's powered on during reset. The "reset hole" is very small, but can be found closest to the screw nearest where the cable plugs in, on the bottom of the controler.

Of course, ps3 can not be used on the ps3 controller. Can not be mixed used.
Or you can dial the Sony service center for advance information, it's better.

I also had this problem running PS2 games. I noticed that when it happened, my bluetooth remotes becames unpaired and could no longer be used to turn the PS3 on/off. Pressing the PS button would not interrupt the hung PS2 game (i.e., it would not give me the options to quit the game, turn the system/controller off, etc.). I talked with the Sony Playstation folks and they suggested resetting the bluetooth controllers (by poking the hole on the backside next to the screw hole). They said sometimes the bluetooth info gets honked. Just before this problem popped up, I was messing around with pairing a bluetooth headset and may have interrupted the pairing. You may have a similar situation, so try resetting your controllers. You may have to plug into the USB port if they won't re-pair after resetting (I did). Good luck!
