Ok, somewhere along the line (prior to my oldest restore point), I "acquired" and Unknown Device in Device Manager - now I know *normally* you can determine what it is by the Hardware & Vendor IDs. Unfortunately, this one has 0000 for each of them. I know it is *something* USB, but can't seem to get any addition info on it It's not something old that is no longer present, as deleting it only results in it trying to re-install itself (and failing). Any help would REALLY be appreciated. I've also run SFC and it returned no issues. Thanks!
