I wonder how this could happen with the following information.

Sonne:~ # udevadm info -x /dev/bus/usb/001/004 | egrep
'SUBSYSTEM|DEVTYPE|ID_USB_INTERFACES'
E: DEVTYPE=usb_device
E: ID_USB_INTERFACES=:070102:
E: SUBSYSTEM=usb

I am going to experiment with corresponding udev rule additions a bit later.
How often do you need to fiddle with the affected rule collection in special
ways on your test and development systems?
