Hi Stuart, I would like to help you with NPEM testing. Currently I have setup with NPEM enabled in Downstream port. It will require to add support for pcieport. Could you add it in next version? I'm also searching for a drive with NPEM to do full validation (when both Downstream and the SSD are reporting capability). If you can point me the model, it will be helpful. Thanks, Mariusz
