Package: libsane
Version: 1.0.18-6
Followup-For: Bug #359797
The patch suggested by Henrique causes libsane.rules to fail to match my
scanner (an Epson CX6600). The problem is that udev sees a subsystem class
of "usb_endpoint" not "usb_device" so the following line causes the bulk of
libsane.rules to be skipped:
SUBSYSTEM!="usb_device", GOTO="libsane_rules_end"
Changing the line to
SUBSYSTEM!="usb_endpoint", GOTO="libsane_rules_end"
allows the rule to match and fixes the problem for me.
I assume that this is a change in how kernel 2.6.20.7 reports this device?
I've attached a udevinfo dump for the curious.

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
