Hey Robert. Thanks again for the response!
As to my Interface, it does not have native ASIO drivers. The microphone plugged into it does, but I don't use those since the interface does not have the drivers also.
Also, I have uninstalled ASIO4ALL in the process of troubleshooting this problem, and it made no difference. As a sidebar, I also use Reaper, and that program has no issues seeing the input device. I used all the driver modes, including ASIO, for many months in MC6 before this problem just cropped up out of nowhere. I do recall that occasionally there would be a small time period when the Input device would not show up, but in those cases, it showed as not working in the ASIO panel and a restart of the computer usually fixed the problem. It never lasted long either way. Now the ASIO4ALL panel shows everything working and connected, as does the preferences for MC6, but I simply can't get it to show up on the track input.
I wouldn't think ASIO4ALL would have anything to do with the problem anyway since it doesn't play into anything when I'm using MME-32 driver mode, which as I noted, has now crapped out. Before that, and after the problem started originally, it was working fine, and WASAPI was not. Now WASAPI is working, and MME-32 not (along with ASIO and WDM).
