Serial I/O driver does the software connection between devices and Operating System which is installed in your PC.
It manages the communication between applications and interfaces provided by drivers which usually runs the device accessories when you mount them.
That is just normal and is necessary because because without this drivers it is just a non-operative machine which can perform but cannot be enabled or accessed to put to use and thus clinge interfacing between operations and put to use for users necessary is really commended by these drivers as it offers necessary files that triggers the device assistants to put to practice when plugged or mounted and it acts like communication bridge through request packets or IRP’s .
