Hi All,
I’m working on supporting D3Cold and wake from D3Cold for the USB H/W we are developing.
From the USB Descriptor the HW/FW is supporting the D3 cold. The USB Bridge Driver for the device is supporting upto D2 State.
When the System is put into Sleep we See the D0Exit() entry point is called with the D2 State not D3.
This Puts the USB into selective suspend state.
ACPI changes indicate that the device supports D3Cold State. which will invoke the _PR3 _OFF function to turn off power to the device, Causing USB to be disconnected.
Question is For supporting D3Cold in USB the PPO driver in this case USB Bridge driver should also be supporting the D3 Cold State?
