  -- First check the different combination of generics below. If your

  -- configuration is not available then add a new one named comb<X+1> (where

  -- X is the value of the last combination defined below) by simply copy

  -- pasting one exicisting combination and changing the generics and component

  -- name. Then add a component decleration for that configuration in the file

  -- grusbhc_unisimpkg.vhd by simply copy pasting the port decleration from

  -- the entity above and replacing n_cc, uhcgen, and nports with their actual

  -- values. Also add the combination of genercis as valid in the function
