Downgrade to 1.0.21-3.fc14 removes error.

The problem remains.

Hi Werner, please enable debugging in the backend driver and run
scanimage again, then attach the output to this ticket:
export SANE_DEFAULT_DEVICE='avision:libusb:001:032'
export SANE_DEBUG_AVISION=7
scanimage
Thanks!

The issue here is that the code to discover devices was moved out of the
initialization routine sane_init() into its own function, but that
function wasn't called in sane_init(). This bug was introduced in this
commit...
commit 37b45c4f76a66f9cd2c3d4bd98dd371dfbda74e5

Moved device init code to sane_get_devices()
Moved device init code from sane_init() to the newly created
sane_reload_devices() function, which is now called from sane_get_devices().
This means that device initialization now happens when sane_get_devices() is
called, not when sane_init() is called.
...and subsequently fixed upstream in this one (after 1.0.22 was out):
commit 33bb529c5f8ca013fb499addc14c7fb229203ea8

Added sane_reload_devices() to sane_init().
Adding sane_reload_devices() to sane_init() required sane_init() to be moved
below the sane_reload_devices() declaration. This restores the original
functionality present before I split the sane_reload_devices() code out of
sane_init() so that it could be called from sane_get_devices().
I'll build an update containing this fix shortly.
