Thanks for using QtSixA!
Disconnect devices
This is the easy part.
You have 2 ways of disconnecting the devices – hardware or software:
Hardware – For the Sixaxis, keep pressing the PS button for 20 seconds. Turn off the keypad with the On/Off switch.
Software – Look at the left of QtSixA, select a device and click the disconnect button – simple.
NOTE: On some old Linux systems, disconnecting a device may not work on Software.
