Dear all,
I've been working with a USB interface on Windows 7 without problems. Some months ago I started to work on Windows 10 pro.
This Windows version is known to have some issues with USB Powering. I did some research and found the following posible power states:
D0 - The working state. The device is fully powered.
D1/D2 - The intermediate sleep states. These states allow the device to be armed for remote wakeup.
D3 - The deepest sleep state. Devices in state D3 cannot be armed for remote wakeup.
My device is set to sleep (goes to D3) after my application is closed. On Windows 7 it would always stay on D0.
However, opening SimpleHIDWrite activates the port miraculously (goes to D0). Does anyone have an idea of what is happening?
I suppose there is a part of the code in SimpleHIDWrite which initializes USB Ports, but how?
How could I replicate this behavior?
Thanks in advance
