 I have a similar problem... Very often, scanning terminates in lag of 
 the program "sane" and a conclusion of messages:
 
 ===========[start]=====================
 ugen0: at uhub4 port 1 (addr 2) disconnected
 All threads purged from ugen0.2
 All threads purged from ugen0.1
 All threads purged from ugen0
 ugen0: detached
 ===========[stop]=====================
 
 Whether will solve this problem a patch offered by *john hood*? Or in 
 last versions FreeBSD(version 6.2-RELEASE and above) it have already 
 corrected?
