This seems to be a problem with the more recent Ubuntu/Dapper which seems to have been solved in the previous version Ubuntu/Breezy and is reflected in the Ubuntu forums.  So I'm not sure what to do new, short of downgrading the whole machine!

Hi 
this scanner is back to grinding and grunting while stationary.  This is with the new sane-backends 1.0.18-1.

It is much better behaved in Breezy via a chroot, but it will only run for the root user.  Better than no scanner!

this is the output from the xterm.  Scanner stopped at line: [plustek] MCLK_FFW = 6 --> 0x0a
I then manually canceled the scanner and pulled the usb cable out. 

$ export SANE_DEBUG_PLUSTEK=20 ; xsane
