Hi,
I have an unexpected behavior with sane_get_device(). In the standard (1.04)
it states (4.3.3) This function can be called repeatedly to detect when new
devices become available. From that I expected that this sequence would work:
sane_init(version, 0);
sane_get_device(device_list,

I also would like to add a generic 'SANE_STATUS_RETRY' for those cases
where the backend has to block during sane_start because it must
ingest the entire image before the size is known.
The standard allows backends to return an unknown

there was a bug in sanei_usb which prevented sane from discovering
newly added scanners. This was fixed in 1.0.20. Unfortunately, some
backends only ask the system for a list of scanners during
sane_init(). I fixed mine, but I bet other backends are

Yep, thats most likely what happened. The epson2 backend can detect Artisan
700 and 800's over the network just fine. There are some issues that cause
it to lock printer up and require power cycle; based on

well, lets re-open the discussion of the return codes. Julien had some
reservations about this technique. I dont have a problem with it, as
long as we formalize it in the standard exactly which status codes
require retry. I also

I think a SANE_STATUS_UNCALIBRATED would also be useful. It would
let a frontend that the scan can start, but will be uncalibrated. This

what will the front-end do with that info? just plow ahead and ignore
it? Thats not really a status, but more of a param of the image data.
I think if you want that info, it makes more sense to turn the last
frame
If no one else gives it a go, I'll have a hand at updating the autoconf
macro. I've not much experience with cross platform locations of those
defines.
I see in my Fedora 11 Linux box that alot of those duplicates are
defined in endian.h (although perhaps hidden by some #ifdef's) and the
