I got a report from someone with a HP4400 that it was actually
an UMAX scanner. He showed me some part numbers and the number
printed on the biggest chip indeed also seemed to confirm that.

Here's part of an e-mail I sent back:

"I stumbled on some scanner chipset info on the following page:
http://umax1220u-sane.sourceforge.net/index.php?ScannerChipsets

It shows that the Umax astra 2000u (USB) scanner contains
a chip with type number 13010057-5071 / 9944 / F7PMO-000.
This is quite similar (at least in formatting) to the
chip number 13010070-5011 that you reported for the HP4400.

The Umax astra 2000u seems to be partially compatible with the
umax astra 1220u.
Perhaps a backend for one scanner would also support the other."

Kind regards,
Bertrik
