Yes, I had not been setting DRIVER_PACKAGE_DELETE_FILES, I checked MSDN
again after posting, and used it, so now it gets removed.

Do you mean that the binaries should remain on Windows 7? In that case the
driver is not uninstalled properly, isn't it? Is it OK to use some kind of
file searching and go and remove it from there?

But then the USBDeview tool shows that the driver still exists on the
system. And in this tool, if I select a particular entry and say "Uninstall
selected devices" the registry entry gets removed. So, shouldn't my
application do the same?

Tim mentioned DevCon, but it doesn't sound like you are using DevCon,
correct? It sounds like you are just uninstalling the driver package and
not the device node itself. I believe DIFxAPI doesn't have support for
uninstalling device nodes, you'll want to use DevCon (or copy the source
from DevCon).

Yes, I'm not using DevCon, I'll check it out.
