	Hello,

	to see what's really going on do:

	export SANE_DEBUG_UMAX_PP=255
	export SANE_DEBUG_UMAX_PP_LOW=255

	and send the debug output of scanimage -L . Get sure that /dev/parport0 can 
be accessed read/write for the user that run the command.

	I wouldn't blame the kernel too fast. My HP3200C is currently working fine 
here on an ubuntu 6.10 . More this bug id 16743 is related to ppscsi devices, 
which are indeed orphaned, but the umax_pp is another thing. It only needs a 
working ppdev. Debug traces will tell what's going on.

Regards,
	Stef
