	when we look at the beginning of the log we have:

	So gimp plugin probe is correctly done with /dev/parport0, while
the aquire uses /dev/usb/scanner0 whichcannot work. It is a gimp,
 xsane gimp plugin or installation bug. Unless you have some settings to 
keep you may try to delete your $HOME/.sane/xsane directory . Also
knowing if stand-alone xsane works would be interesting.
	Last, check that you don't have several umax_pp.conf files, with
one configured with 'port /dev/usb/scanner0'. Or one with a few port
options. I know that the 9.2 mandrake panel adds a 'port' line every time
without removing existing ones when you configure your scanner.
