	Hello,

	I had a rapid look at the code. There are other debug traces that would be 
interesting. The backend uses sanei_lm983x_* functions to communicate with the 
scanner. So by running scanimage like:

SANE_DEBUG_PLUSTEK=255
SANE_DEBUG_SANEI_LM983X=255
scanimage -d plustek >scan.pnm 2>debug.log

	We'll have more traces, including registers content read from your scanner 
which may be returning an unexpected value.

Regards,
	Stef
