Problem solved, folks! I found a small icon in the upper right-hand corner of
my screen that I hadn't noticed before. I clicked on it, and a menu appeared
that had all the necessary info and commands I needed to get my mobile adapter
working with mythbuntu just splendidly! The only problem was that I downloaded
so many updates and upgrades that mythbuntu got messed up, and now I'm gonna
have to reinstall mythbuntu from scratch! Oh, well, live and learn . . .
