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
