Ah, the plustek backend. My HP 2200C began, suddenly, to exhibit this
type of behavior some weeks back. I asked on -questions and received
no reply, so I assumed it was best to file a bug report with the
backend maintainers. That went over like a lead balloon; not that it
was their fault, it just went badly. I finally gave up and purchased a
new scanner.

The last thing I heard about my bug report from the backend
maintainers was "It works for me."

I was torn between attributing it to some weird issue with FBSD's USB
bits, and a bug in the sane backend code; but I lack the clue to know
which. Prior to the backend update, outlined below, the HP 2200C
worked adequately.

2005-12-18: SANE-Backends-1.0.17 has been released. Changes since
1.0.16:

    * New backends: hp4200 (HP ScanJet 4200), lexmark (Lexmark X1100
      series), mustek_usb2 (Mustek BearPaw 2448 TA Pro)
    * Updated backends: artec_eplus48u, avision, canon, epson,
      fujitsu, genesys, gt68xx, microtek2, mustek_pp, plustek,
      plustek_pp, sm3600, snapscan, umax_pp.

I'd give you the bug number, but they closed and tossed it.

Good luck, and I hope it works out....
