     It is not a special case for you. Even if you attach any webcam
you will find that sane-find-scanner will show it's USB ID's.
What sane-find-scanner does
1)it searches for all attached devices right from scsi devices to usb devices.
2) In case of usb devices sane-find-scanner program calls
check_usb_file function in sane-find-scanner.c
3)check_usb_file will open each attached usb device and then collect
USB ID's and it will show you that output.

So no wonder.
