Sorry about that. I don't think there is a function to check whether or not you are suspended, but you should get a SUSPEND event from app_usbd when the host enters suspend, and the RESUME event when suspend is over.

Then you can keep track of the suspend state in the application in case you need to check it later.

No I have not removed and added the CDC instance.

Do you have a response for my second question?

Unfortunately the developer most familiar with the RWU feature is out in vacation at the moment, but I will help you out as best I can in the mean time.

You say that unregistering rwu doesn't work properly, but have you tried to remove and append the CDC instance again?

We have no examples showing how to use the remote wakeup feature unfortunately.
