we are doing stability test for android device. It means we are just pinging device ip address. After test has passed, when we connected device with usb to the host "adb devices" not working.
When I checked the logs,I found below lines [161528.696960, 1] android_usb: Cannot enable 'none' [161528.709930, 1] musb-hdrc musb-hdrc: gadget android_usb D+ pullup on [161528.732116, 1] init: Service 'adbd' is being killed...

The above property has triggered means "It has disabled USB when switching states". so we are getting "android_usb: Cannot enable 'none' ". Incase of device connected to ethernet, it is in "none" state. And then when device is connected to host with usb it is not detecting. I donno where I have to reset the status or something.
