So your scanner is not detected by the kernel at all, only the root
hub. Either the scanner is not plugged in or defective. Theoretically
there could be a bug in the Linux kernel but as the root hub is
detected this is rather unlikely.

It is mounted, otherwise you couldn't "cat /proc/bus/usb/devices". And
you have USB support, otherwise the hub wouldn't be detected.
