I can only guess it's the device presented to the OS when it hasn't
been unmounted properly... 

  http://focus.ti.com/docs/prod/folders/print/tusb6250.html

Shows it to be a USB/ATA bridge of some sort -- Texas Instruments.  Why
Fedora seemed more adept at seeing the device may have been purely
coincidence.  I'd assume I could get the drive in a funky state so that
Fedora only sees this TI device as well... though so far I've been
unable to reproduce (on Fedora). :)
