# Disconnect (power off) dualshock 4 controllers from linux cmdline
# This command finds and turns off all currently connected dualshock 4 controllers
# by sending a usb reset signal to the offical dualshock 4 usb wireless dongle

# Reason: because otherwise you have to hold down the PS button for 10-15 seconds
#         ...which is a really long time to wait!

# Note: USB device id is for only the official sony dongle.
# Other 3rd party dongles will have a different usb device id
