I have a tablet and a LAVA SimulCharge adapter.

I would like to disconnect all USB devices when power is disconnected and reconnect them when power is connected.

Is this possible to do via changes to init.usb.rc ?

(My device is Galaxy Tab S2 LTE android 6.0.1 rooted via SuperSU systemless root.)

I'm thinking something like

on property:sys.usb.config=*accessory?* write /sys/class/android_usb/android0/enable 0

on property:sys.usb.config=*charging?* # or is it charging,accessory ? write /sys/class/android_usb/android0/enable 1

Reason is that when the charger is disconnected from the LAVA adapter, this prevents the tablet from sleeping and drains baterry.

  • Try this. If that works out would be possible to automate – beeshyams Sep 01 '16 at 13:49
  • sorry.. tried echo 0 > /sys/class/android_usb/android0/enable and didn't work. ES File Explorer shows that this file has value 0, yet the USB is device is still connected and wakes up the tablet. – Madushan Sep 02 '16 at 07:36
