I used to use my ps3 controller to play games, and a couple of days ago it stopped working. I get this message during boot up (after BIOS):
[ (some numers)] sony 0003.054c.(more numbers): can't set operational mode
qtsixa still recognizes the controller being plugged in. My best guess is there was an update to a dependent or repository or something.
I also tried to connect a different ps3 controller with a different cord in a different USB slot - no change. I have also tried resetting them both with the little button on the back.
lsusb in terminal and in usb port 7 it says:
Sony Corp. Batoh Device / PlayStation 3 Controller
Jstest & antimicro don't recognize that the controller is there.
