Hello,

/boot/config-2.6.22.17-0.1-default  contains:

.
.
.
#
# USB support
#
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_ARCH_HAS_EHCI=y
CONFIG_USB=m
# CONFIG_USB_DEBUG is not set

#
# Miscellaneous USB options
#
CONFIG_USB_DEVICEFS=y
# CONFIG_USB_DEVICE_CLASS is not set
# CONFIG_USB_DYNAMIC_MINORS is not set
# CONFIG_USB_SUSPEND is not set         <---------
# CONFIG_USB_OTG is not set
.
.
.

I'm not sure that it is, what you searching. I use:
Suse10.3  2.6.22.17-0.1-default

By the way: I've seen the same problem (scanner head starts to 
shake) on a Window-PC. (My scanner was earlier on a other PC.)
