With the current implementation of sanei_usb, the libusb:* identifiers in SANE are not persistent - they change each time the scanner is disconnected and connected again. Because of this, saved preferences in the frontends do not work reliably - a reattached scanner will appear as a new device. With the kernel driver such problems can appear only if someone has more than one USB scanner.
