It has two motors that all are the same size .

Visual vibration part of the pad plug-in uses only left motor to provide rumble effect .
Here is my kernel log ,when i connect my gamegad.

No such effect
As you can see pcsxr pad plug-in uses FF_RUMBLE (strong) instead of FF_PERIODIC (FF_SINE) .
Because of that , in the game only the left motor rumbles.
How can i fix the problem ?
Could someone write a patch to prevent this issue ?
(i don't know programing languages , but i think i should change some code in the plugins/dfinput/pad.c source file .)
(I installed pcsxr from https://aur.archlinux.org/packages.php?ID=40720 )
Comments: ** Comment from web user: edgbla **
It is not true, see the fftest source code:
```
/* a strong rumbling effect */ <- 4 !!!
effects[4].type = FF_RUMBLE;
effects[4].id = -1;
effects[4].u.rumble.strong_magnitude = 0x8000;
effects[4].u.rumble.weak_magnitude = 0; <- small motor is disabled
effects[4].replay.length = 5000;
effects[4].replay.delay = 1000;
if (ioctl(fd, EVIOCSFF, &effects[4]) == -1)
perror("Upload effects[4]");
/* a weak rumbling effect */ <- 5 !!!
effects[5].type = FF_RUMBLE;
effects[5].id = -1;
effects[5].u.rumble.strong_magnitude = 0; <- big motor is disabled
effects[5].u.rumble.weak_magnitude = 0xc000;
effects[5].replay.length = 5000;
effects[5].replay.delay = 0;
if (ioctl(fd, EVIOCSFF, &effects[5]) == -1)
perror("Upload effects[5]");
```
FF_RUMBLE can be used for both motors simultaneously.
