You are right, my version of udev 108-0ubuntu4 does not include the key "BUS".

I have searched the release notes of udev and found that in version 098 some 
keys were renamed (incl. BUS -> SUBSYSTEMS) so they may not be supported in 
newer versions anymore.

Hence it seems quite difficult to propose a universal advice valid for all 
systems apart from
1) check dmesg after plug-in to find out which usb device was assigned (e.g. 
usb 2-1)
2) check udevinfo -a -p /sys/bus/usb/devices/2-1
3) use those keys in your rules.

udevmonitor will print the received events for:
UDEV the event which udev sends out after rule processing
UEVENT the kernel uevent
