Windows XP performance problem with USB scanner

[F1!]

Hi guys, I plug in a scanner to my Win XP and very frequently, when
the scanner is not in use, the scanner shuts down to save power. My XP
performance then goes down drastically. A friend said that XP keeps
checking all USB ports to see that applications plugged in are active
and that this takes a lot of cycles. Is this true? Any way I can
improve performance? Thanks Tom

Check Start> Run> services.msc
If the Windows Image Acquisition service is set to automatic, try changing
it to Manual. May need to restart the system to see a difference in
performance.

Go to Control Panel - System - Hardware - Device Manager and look in
USB Controllers for the USB Root hub where the scanner is connected
(double click each, and the Power page will tell you the devices
connected). Having found it, on the Power Management page, uncheck
'Allow computer to turn device off to save power'. Indeed on a desktop
machine you might as well do that for all the USB hubs
