Excellent!

1. I downloaded an integrated the drivers with my SANE setup. I built
the Coolscan stuff static and FTPed it to the scanner machine, which
is a very minimal Linux install.

2. I checked find-scanner (looked good so far)

3. I ran scanimage -L and saw the Coolscan listed (yeah!)

4. I tried scanimage > example, but it locked up the SCSI on my test
machine, and I had to switch off the Coolscan. The main drives on
that machine are SCSI, so this was very scary. I shutdown & restarted

/* I have a DPT card, using Linux 2.2.6 EATA card drivers. It wouldn't
let go until I physically switched off the Coolscan :( */

5. I commented the AutoFocus code out of your driver

6. I re-built, re-transferred and re-installed

7. I ran scanimage > example, and this time I got some data!

I'll write a second mail when I've tinkered with some more values and
taken a look at the code a second time. However, I'm already impressed
that I actually got DATA out of this first alpha driver.
