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

If I issue scanimage -T, it will start clicking instantly
# scanimage --output-file=scan.jpg -vvvvvv

get an I/O error. I will continue to troubleshoot, but wanted to get
this out here in case someone has an answer
