Netadapter driver doesn't go to low power when com port driver is installed. RRS feed

  • Question

  • I have a netadapter driver. Power event call backs(D0 Entry and D0 Exit) are implemented. When system goes to low power state (sleep) netadapter also goes to low power - D0 Exit call back is being called. But if i install WWAN virtual comport driver along with net adapter driver then netadapter doesn't go to low power - D0 exit callback not being called. 

    Comport driver doesn't have any implementation of Pnp and Power management.
