OM,
Steinburg is likely the Generic USB driver Windows found and OP says works ..
I wouldn't doubt that a restart (with the the Mixer ON) allowed Windows/RB to find the correct input.
I haven't seen any screen shots since he said he got it working.
There is the screenshot of the track lineup above that indicates the Harbinger drivers are being sourced. Everything else is the same except now the input driver has been updated to show the same change I made to its name in windows by now reading Harbinger and now BB is showing both the input and output drivers under the ASIO driver menu.
