Hi
My laptop frequently connected to industrial devices through industrial protocol Modbus, which requires a software Driver Manager.
It was working properly, someday the connection failed and never come back even trying to un-install/re-install the software few times.
I'm not sure whether it is caused by either a windows update or laptop software/bios update(Lenovo W541).
But the connection is ok under XP mode except automatic disconnection occasionally.
Now I guess it is something to stop installing a modbus driver after Driver Manager is installed because it shows empty in Driver window.
The below snapshot shows nothing in driver window.
Modbus driver is installed in Driver Manager under XP mode.
Is there anyone encountering the similar situation?
