    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!

    It might be useful to get a spec sheet for the computer and check the list of devices with the Device Manager list.
    I once had a similar issue with a D630
    turned out to be a smartcard reader
    which I never knew existed till I went thru the process

    I've still never used it
    but at least I got rid of the "!"

    Have you been messing with any bios settings? You might have turned something on by accident..

    Well, oddly, it turned out to be the USB drive I had set for the exclusive use of ReadyBoost. I happened to remove it and the device was removed as well. I put the drive in another system and it wasn't recognized as a ReadyBoost, so I formatted it, put it back in my system, and was able to re-configure it for ReadyBoost.

    Very odd, but not the 1st time RB has screwed up a USB drive on me - it literally "killed" the last drive I used.
