Android USB devices (eg. /sys/class/android_usb/android0/)
What: /sys/class/android_usb/<android_device>/state
Date: Feb 2024
Contact: Neill Kapron <nkapron@google.com>
Description:
The state of the USB connection. This attribute is likely
redundant with the /sys/class/UDC/state attribute, and should
be deprecated/removed when userspace can be refactored.
Change on the state will also generate uevent KOBJ_CHANGE on
the port with the new state included in the message as
"USB_STATE=<STATE>". Note this is not the correct usage of
uevents, but necessary due to the requirement to maintaine
userspace API compatibility.
Valid values: CONNECTED, DISCONNECTED, CONFIGURED
