Same problem!

In my case it happens with retrolink N64 controller since the beginning with 4.1.
I added the ImputAutocfg.ini file as I had it working propperly in the 4.0.2 version and it doesn't help. In fact, it should help PS3 controller work and it doesn't neither. This is the content of the file as I have it:

[Generic USB Joystick ]
plugged = True
mouse = False
AnalogDeadzone = 4096,4096
AnalogPeak = 32768,32768
DPad R = axis(5+)
DPad L = axis(5-)
DPad D = axis(6+)
DPad U = axis(6-)
Start = button(9)
Z Trig = button(7)
B Button = button(8)
A Button = button(6)
C Button R = button(1)
C Button L = button(3)
C Button D = button(2)
C Button U = button(0)
R Trig = button(5)
L Trig = button(4)
Mempak switch = key(109)
Rumblepak switch = key(114)
Y Axis = axis(1-,1+)
X Axis = axis(0-,0+)

[Sony PLAYSTATION(R)3 Controller]
plugged = True
mouse = False
AnalogDeadzone = 4096,4096
AnalogPeak = 32768,32768
DPad R = button(5)
DPad L = button(7)
DPad D = button(6)
DPad U = button(4)
Start = button(3)
Z Trig = button(10)
B Button = button(15)
A Button = button(14)
C Button R = axis(2+)
C Button L = axis(2-)
C Button D = axis(3+)
C Button U = axis(3-)
R Trig = button(11)
L Trig = button(8)
Mempak switch =
Rumblepak switch =
X Axis = axis(0-,0+)
Y Axis = axis(1-,1+)

Is any of this wrong? Does anybody know where could be the problem?
