Some time ago, sane used the scanner kernel module to communicate
over USB with quite a lot of USB scanners. Nowadays, the scanner
kernel module has been removed from the kernel and sane now uses
libusb. Libusb in turn relies on the usbfs virtual file system
in /proc/bus/usb.
So your kernel needs to have usbfs configured in and usbfs needs
to be mounted (e.g. in a boot script).
If lsusb can see your scanner, then usbfs is probably OK.
If sane-find-scanner can see your scanner then libusb is probably
set up OK too.

I have no idea.

Kind regards,
