My pelican adapter from ps2 to ps3 via usb will not work for dualshock controllers and will not turn on.

turn off the ps3 plug control in via usb turn computer on with center control button

Most likely Becuase it isn't a dualshock controller. Or if the game is on the PS3 and your using a PS2 controller. But sometimes you may use PS2 controllers on the PS3. but sometimes some games won't let you use the controller do to the lack of usage of the dualshock controller. I hope this helps

I picked up the folling troubleshooting tips from the PlayStation Knowledge Center. I know it may seem silly or insulting; This is not my intention. Problems like this are usually just little things you're over-looking. Give thest tips a shot, one by one, and see if your solution is in here. If it isn't, message me back here & we'll try something else to get your controller working, ok? By the way... Is it a sixaxis controller or dualshock?

• Verify if the SIXAXIS or DUALSHOCK 3 wireless controller works with the USB cable.
  
• Verify that the SIXAXIS or DUALSHOCK 3 wireless controller's battery is charged.
  
• Attempt to pair the SIXAXIS or DUALSHOCK 3 wireless controller to another PLAYSTATION 3 system. This helps determine whether the problem is with the system or the controller.
  
• Attempt to connect another SIXAXIS or DUALSHOCK 3 wireless controller to the PLAYSTATION 3.
  
• Move closer to the PLAYSTATION 3 system. The maximum range for Bluetooth is 30 feet.
  
• Make sure you have less than seven Bluetooth peripherals paired with the PLAYSTATION 3.
  
• Unplug any other USB device plugged into the system when pairing the SIXAXIS or DUALSHOCK 3 wireless controller.

its all about dualshock 2 controllers. if you get these, it will work for all games. see, a dualshock 2 controller is like the head of a pack. it works for everything. you probably have a dualshock or just a ps1 controller. try buying a dualshock 2 controller, and you shouldnt have that problem anymore. proud to be part of your help.

there are several ps2 to usb adapters out there, many made expressly for connecting the dual shock 2 to the ps3. they cost anywhere from around $5 to $20. i have one myself and it works very well.

Amazon.com has several listed - or you can search anywhere for 'ps2 to usb' or 'ps2 to ps3' and you should find something that will work - although as always read the reviews on the product first.

No, it's not possible to hook up sixaxis to PS2. Sixaxis is a part of DualShock 3 for PS3 which is an optional feature in the PS3 games. Playstation 2 controllers run off of DualShock 2. So sorry, but you're gonna need a PS3 for that.

idk

Usually, all dualshock controllers malfunction after a year or so. Do not be surprised.
