	Hello,

	you may check SANE's config.h to check if ppdev is really built in. Then
you may also look at the /dev/parport* devices to see if they can be used by
any user:

on my PC they look like:

crw-rw-rw-   1 root     root      99,   0 Feb 10  2000 /dev/parport0
crw-rw-rw-   1 root     root      99,   1 Feb 10  2000 /dev/parport1
crw-rw-rw-   1 root     root      99,   2 Feb 10  2000 /dev/parport2


	If everything looks OK, don't hesitate do send me the output of

	./umax_pp -p -t 255 2>probe.log

	where 'umax_pp' is located in the tools subdir.

Regards,
	Stef
