The idea of a better power on the USB connector should be the solution, i'll try as soon as possible. But i've only one arcade stick connected directly on my Raspberry 1, the other USB connector is unused. I'm gonna try the new config also and tell you if it works.
Thx a lot for your answer ;), your english is really fine I've tried to execute your commands with the configuration of the recalbox.conf :
controllers.ps3.enabled=0
controllers.ps3.driver=official
controllers.xboxdrv.enabled=1
controllers.xboxdrv.nbcontrols=2
My joystick is a PS3 one's but i've tried this configuration to test if it could solve the problem. Here is the pastebin result of the command lines after editing /boot/cmdline.txt and reboot : http://pastebin.com/K16tYd9c In EmulationStation the PS3 joystick doesn't respond. Same behaviour after a new reboot with the dwc_otg.speed=1 option. Then with another recalbox configuration in recalbox.conf :
controllers.ps3.enabled=1
controllers.ps3.driver=official
controllers.xboxdrv.enabled=0
controllers.xboxdrv.nbcontrols=2
The result is also a freeze of the controller, no buttons responds, but the list of input is different and the values of the axes are not fixed to zero like the virtual gamepad xbox : http://pastebin.com/V1Lx3VcD In EmulationStation the PS3 joystick doesn't respond also, like with the other configuration : dwc_otg.speed=1 Another suggestion ? It seem that the problem is about the USB chipset. I'm not sure some post's is referencing the "VIA" chipset as the only way to connect this sort of PS3 controller, i wish this is not the real problem ... 
Hi all, I've exactly the same problem as Steve with a PS3 MadCatz TE Round2, the buttons doesn't respond. I've created the "99-madcatz.rules" and modified the chmod rights correctly, then reboot the pi. nano /etc/udev/rules.d/99-madcatz.rules write into the file : SUBSYSTEM=="input", ATTRS{name}=="MadCatz PC USB Wired Stick 8838", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1" save the file and modify the rights : chmod 755 /etc/udev/rules.d/99-madcatz.rules then reboot I've used 755 in order to give the same rigths as the others rules (99-sixpair.rules, 99-wiimote.rules) in the directory /etc/udev/rules.d/ Here is my pastebin of the command line you advise to Steve : http://pastebin.com/RbtR0aUf The evtest command line display always this pastebin, even if the fightstick is used : http://pastebin.com/JMX4in5f I don't know if it's not a problem of hardware compatibility ? If you've got any suggestion or sample of other config file, or command line to solve this problem i'm really interested in. I've tried to test any config option from the board on the left side "LP" / "DP" and "RS" no changes occured in the behaviour of the PS3 MadCatz TE R2 when i plugged in the usb on the raspberry. Thx for your precious help Note : sorry for the multiple "EDIT" i don't really arrived to customize my post display ... as i'd like to.
