I can't yet define exactly what actions hang up my scanner. At least, 
when I scan continuously, using the same program, all work well.
By the way, successful scanning adds three lines like this to the kernel 
ring buffer:
usb 1-1: usbfs: interface 1 claimed by usblp while 'xsane' sets config #1
(or 'scanimage' instead of 'xsane')

Actually, removing of old files was aimed to solve a problem when 
scanimage and xsane could only be run from /usr/local/etc/sane.d (i.e. 
scanimage couldn't find the scanner, but after 'cd 
/usr/local/etc/sane.d' it could). At first it helped, but after reboot 
only xsane could run from anywhere. This isn't a big problem, but the 
fact remains.
