Ok, well finally I placed the 7450 from the dusty corner onto my desk.

The only problem I could encounter (using my SVN:HEAD code of course) was,
that the calibration was optimized away entirely. And thus consecutive
flatbed scans made this scanner hang.

I commited this optimization out for now (I need to rethink for what
model I added this). Commited as revision 286, BUILD 178.

1bit, dither, gray and color work well here - in flatbed and ADF mode.

Can you retest with the svn HEAD code please? Please mail me a log with
SANE_DEBUG_AVISION=8 if there is still a problem (yes 8 instead of the
usually requested 7, since 8 logg more USB low level i/o ...).

Btw. do you use the scanner via USB or SCSI? I tested USB today.

Yours,
