[PATCH v3 2/5] DeviceInfo: Add connection logic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Chen Ganir <chen.ganir@xxxxxx>

Add connection logic to the Device Information Plugin. When the
driver is loaded, it will request a connection to the remote device
and release the connection request when destroyed.
