  Like others have no doubt pointed-out by now: It seems you have a U3
device (E.g. SanDisk Cruzer or similar). The second drive's not there
because Windows "infected it", but has been there from the start.
  The device's microcontroller presents two USB drives to the host: A
mass-storage device ("Flash drive") and a CD-Rom. As far as I can
tell, you still can't remove this directly from Linux.

  The (supported) Windows driver's here:


  They used to support McOs too, and the removal tool's available from
the Wayback machine here:


  It's a little annoying as you have to "install" the utilites to be
able to uninstall the U3 software. No idea if it works under current
McOs releases.

  Nevertheless, I highly recommend removing the U3 system as soon as
you get one of these drives.
