I haven't investigated processing specifically for scanning.  I've been just 
going along
as I did before.  My combinations include (using distilled water to mix all 
developers and
Photo-Flo):

Agfa APX 25 in Rodinal 1:25 or 1:50, depending on the contrast of the scene;
 
Tri-X or HP5 in FG-7 1:15 when rated at 400/500 ISO;

Or FG-7 1:15 with a 9% solution of sodium sulfite, for a rating of 800 ISO;

FP4 in FG-7 1:15;

FP4 in Microdol-X straight;

Verichrome Pan in FG-7 1:15 or Microdol-X straight;

Kodak HIE infrared in FG7 1:15

My times at 68F vary; I develop by inspection - when the density looks right 
under
the green light, I put it in the fixer. You can check out my gallery and 
decide for yourself
if my scanned negs look good.
