Ick. Scanning books to OCR will be punishingly slow if the driver (TWAIN driver? Imitation Photoshop plugin? whatever) remains flaky. I was fine with having it not installed by default, although the Readme installation instructions were not helpful. But it gives me fits that the software connection fades in and out.
And enough stuff has now been sold me with sleazywillfully optimistic compatibility assurances that I don't even want to buy the driver-upgrade CD for the scanner I did settle on, although that is the most likely fix, and it's not terrifically expensive. Compared to the scanner and an upgrade to the OCR software, not expensive; but the HP website doesn't list what's been upgraded, or for what OSes, so it also might not be at all useful. And (huff) really, they ought to be able to pull that info out of their fixed-bug database.
