There are no hardware controls on any scanner I've used. At least there are no physical knobs to turn. Presumably, the software provided by the manufacturer is actually controlling some hardware internally when you adjust the software exposure, gamma, etc.

In SilverFast, you can take a prescan, then have the software show a histogram. If you adjust the black point to just below the darkest data, and set the white point just above the brightest data, then it will spread the range of density values on the film across the range of pixel values. If it does that by adjusting the hardware, it can do a better job than doing the same thing in Photoshop.
I typically make a liberal adjustment in the scanner software, then fine tune it later in Photoshop using the levels tool or for more control the curves tool.
