[sane-devel] Fujitsu M3093DG duplex ADF failure

[Mikolaj J. Habryn]

I've just bought an M3093DG from ebay and have been poking at it with
sane. Happy to report that detection and ADF scanning work just fine.
The only thing that doesn't is duplex scanning.

Specifying --duplex back results in an endless supply of 37 byte files
purportedly containing scans but being generated at many per second.
--duplex both or front yields:

orthos:~/scan# scanadf --source adf --duplex front
scanadf: rounded value of br-x from 215.9 to 215.893
scanadf: rounded value of br-y from 297 to 296.994
scanadf: sane_start: Invalid argument
Invalid argument
Scanned 0 pages
orthos:~/scan#

The sane-fujitsu man page claims this model is generally supported but
it isn't clear if the duplex unit is expected to work. Can somebody
confirm whether or not it should? I'm running on a Linux 2.6.11-rc4
kernel if it makes a difference.
