Send uevent when received control request 51 and 52
to help debug and recover when the handshake not finished.
Description about control request 51 and 52
control_request 51 :
Send a 51 control request ("Get Protocol") to figure out
if the device supports the Android accessory protocol.
A non-zero number is returned if the protocol is supported,
which represents the version of the protocol that
the device supports (currently, only version 1 exists).
control_request 52 :
If the device returns a proper protocol version,
send identifying string information to the device.
This information allows the device to figure out
an appropriate application for this accessory and
also present the user with a URL if
an appropriate application does not exist.
The detail description could reference below link.
