hi All, I would like to know how .suspend and .resume in device driver invoked where ACPI is not used. What I meant is suppose you have USB not connected then what is the state of the device driver. Is the .probe function running continuously in the background. -Anand Moon _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
