Thanks for the discussion! I changed to the WDM driver. New nomenclature is:
"Left Scarlett 18i20 USB 1/2"
"Right Scarlett 18i20 USB 1/2"
"Stereo Scarlett 18i20 USB 1/2"
"Left Scarlett 18i20 USB 3/4"
etc........
IMO, this is equally as senseless as the ASIO, although it does show an even-number, which could be considered a bonus. Since Focusrite spells out the use of the ASIO driver, I'll switch back, and hope that one day, Cakewalk or Focusrite or whomever will start providing realistic input names...
