Hi Yuri,

Can you please define more what you mean by "freezes the system"?

Does it panic the kernel (which either reboots itself or drops you to a
debugging console)?

Does the command line just not output anything and not return to the
prompt? In this case, maybe a Ctrl+c will exit the scanimage program and
return you to the prompt?

Or does it freeze your scanner (I.e. The impact is on your scanner, leaving
your FreeBSD machine running fine)?

Regards,
Ben
