I edited dll.conf and also umax_pp.conf for port 0x378 as I didn't have /dev/parport0. Then I did rpm -e sane-backends-1.0.8 and compiled src 1.0.9. Now it works as root.

I'm sorry, but I can't go beyond. My Astra 2000 is dead, and I can't check it under MDK 9.0. As I said, some time ago work very fine with MDK 8.2.
