yes, it does with no problems since it is connected straight into a usb
port of the pc NOT into a usb powered hub.

I did not do any win driver extraction - as a matter of fact I do not (I
mean the system) even have /etc/share/sane/snapscan file. the hardy file
system is exactly as provided by distro as far as scanners go.

my scanner does not have any switch for powering up or shutting down, it
is on or in a hibernation state all the time if connected to a usb port
-it  is powered down/up by the pc software via the usb port.

the problem  that I was having is for sure related to the usb powered
hub itself that did not reset properly the scanner after powering down
and up the pc; The way this scanner is designed, for successful
operation, it shuts down (powered down) after the usb connection is
removed - this thing does not happen at all if the usb is pure and
simple manually disconnected - it does so ONLY if the software ganerates
a power down sequence (and obviously a power up sequence).

 why doesn't  the scanner get these sequences correctly via the usb
powered hub? only via pc usb ports ? mystery so far.

so, I pure and simple left the scanner connected to a pc usb port - it
powers down correctly when the pc is shut down and also, v important to
note, it has a built in timer that after approx 10 minutes of idle time
it goes into hibernation and wakes up whenever asked to perform.

I'm v happy about its performance; I have it for more than 6 yrs and
never let me down. I tried to investigate further why it works without
flaws when connected to pc usb ports and NOT at all when connected to
powered hubs - so far I couldn't find any answers --> AGFA is not in
scanners business any longer.
