the usbmon devices need a subsystem entry. The best way to me seems to
attach them to the USB bus where all host controllers are already
listed.

And btw. /dev/usbmon1, /dev/usbmon2 etc. is the preferred naming
nowadays. The subdirectory style isn't really used anymore since devfs
is finally gone. However udev can always overwrite the final name.

Marcel
