Question: How can I know when data arrives at IN endpoint so that the host application can read it?
Answer:
Device cannot itself initiate any transfers. Host has to check the status of the IN Endpoint if there is a data available to be read. One way is to send a vendor command to read the byte count of the IN endpoint on a regular interval. An example is attached.
