I don't own such a device. I got a report via the "add unsupported
device" form. I've asked for USB vendor/product ids but haven't gotten
an answer yet. I'll cite the mail so you can ask the author if you are
interested in details:

| 1. Your email address:
|    'dkindler at dragonfireinc dot net' (modified by me)
| --
| 2. Manufacturer (e.g. "Mustek"):
|    'Hewlett Packard'
| --
| 3. Model name (e.g. ScanExpress 1200UB):
|    'Scanjet 8200'
| --
| 4. Bus type:
|    'USB'
| --
| 5. Vendor- and product id:
|    'HP Scanjet 8200'
|    
| 6. Chipset (e.g. lm9831):
|    'HP Avision C7'

| 7. Comments (e.g. similar to Mustek 1234):
|    'I'm impressed with this HP scanner.  It's a true 4800 x 4800 dpi
|    optical resolution.  I've
| +scanned resolution targets, and it's quite good (although not quite
| up to the 5 micron size you'd
| +think a 4800 dpi implies).  I'd like to have scanner control to do
| some custom work with this
| +machine.   I've done a lot of work on it, have disassembled and
| reassembled it, and have photos of+the boards, etc.  Please tell me if
| you want these images, and where to send them.
| 
| We have not tested with SANE yet, because this scanner appears to use
| different drivers from any of+the SANE supported hardware.  We could
| run tests with a Mandrake 9 Linux install if you'd like.
| 
| How do you go about getting the technical information to write a linux
| driver for an HP scanner?
| +If you need to buy a technical manual, we would consider paying that
| fee to support your effort.
| +We're not programmers, but we'd love to have more control over this
| machine than we can achieve
| +with the HP scanning software.

Bye,
