Update to my mailing below (I deleted it before it was approved to the
list)....
It definitely has to do with what's going on during the sane_read API
function.
If I issue scanimage -T, it will start clicking instantly
# scanimage --output-file=scan.jpg -vvvvvv

Device will scan with the scanimage command but towards the end of the
sheet, when I assume transferring data, the scanner starts ticking and I
get an I/O error. I will continue to troubleshoot, but wanted to get
this out here in case someone has an answer
