That's correct. Device files are usually in /dev/.

Possible reasons for device files in /dev/usb/
- you are using devfs and
* no USB device is connected
* a USB device is conncetd but not detected for some reason
- you are not using devfs and haven't created the device nodes yet.
cd /dev/ ; MAKEDEV usb ; in this case.

Which scanner exactly? I would like to add its ids to the kernel
What do you mean by "non Sane"? Not supported by SANE?

0x06dc/0x0014 doesn't seem to be known by the kernel scanner driver,
therefore the "Driver=(none)" in the I: line.
F.I.T = "Foxlink Image Technology Co., Ltd.". Never heard about this
Run "rmmod scanner; modprobe scanner vendor=0x06dc product=0x0014". If
you use devfs, the file /dev/usb/scanner should exist now.
