I append the results of my sane-find-scanner run. It does find a
scanner, reporting
    found USB scanner (vendor=0x03f0, product=0x3905) at libusb:001:016

Similarly, lsusb says:
    Bus 001 Device 016: ID 03f0:3905 Hewlett-Packard 

I searched the sane web page of product listings for the string "3905", 
but no hits.

I browsed through the sane listings last night. My scanner criteria are:
- flatbed
- automatic document feeder, duplex, >= 50 pages
- costs under 1k$

I discovered that
- There are many scanners on the market of this form. Here's an example:
  http://www.newegg.com/Product/Product.aspx?Item=N82E16838104036

- Sane doesn't typically support current models. For example, every such
  model that is sold at Newegg isn't supported by sane.
  This includes the current offerings of HP, Canon, Fujitsu & Xerox.

- The models that sane *does* support are typically models that are no longer
  sold (e.g., if you check on Amazon).

The one exception seems to be an Epson scanner, of somewhat lower resolution. 
Sane seems to be one generation behind, across the board, in this niche. 
Am I missing something?

Here is the diff between running sane-find-scanner -v -v with the scanner
plugged in & with it not plugged in:
