no, the host controller by itself will not poll the device asking if it has data. it is up to you to always have a pending transfer on the IN endpoint so that the host controller is always asking for data. your device can then send back data when it has something to send.

Thanks, that did it. If I may, have another question.
Using a single bulk address with both a IN and OUT endpoint. I am a little
unclear on the device sending data to the host. When does the host send
notifcation to the device that it is expecting data? In particular my device
is monitoring some engine functions and based on some conditions will
asynchronously send status data to the host. I know a USB host initiates IN
data transfers. Does it periodically ask a device if it has any data to send?

if you downloaded the latest WDK (6001) it comes with KMDF 1.7, which would
be in wdfcoinstaller01007.dll. even then, you might have the 1.7
coinstaller b/c there was a servicing problem which delayed the release of
the coinstaller. You can download the kmdf coinstaller separately,
