Another 9.1 scanner problem

This one's a Mustek parallel port scanner and so has to be set up by hand. Probably I've got some device or kernel module wrong. So any suggestions might help. This is the test (as root) uyea:/etc # export SANE_DEBUG_MUSTEK_PP=128 uyea:/etc # scanimage -L [sanei_debug] Setting debug level of mustek_pp to 128.
