Hi, I am new developing KMDF Drivers and I would like to know if somebody could help me.
This is what I have:
I Have a Usb to Serial Converter, from one side Usb and the other one Serial, for purpose communication.
In this moment we have a FDO (usbser.sys) that makes the usb to serial translation and a Filter DO that makes the flow control.
This is the problem:
The problem is that we need to make that the driver supports Remote Wakeup from the Device, but we can not access to the FDO(usbser.sys) to add those Power Management properties.
This is my possible solution:
My possible solution is to develop a PDO to enumerate the devices that we attach to the host(PC), and now that we have PDO that has the ability to wake and be awakened we could add those Power Management properties to the PDO to be able to wake up the host(PC) from the device(Usb2serHardware) as the mouse does for example.
