Adding sysfs symlinks for usbfs

Is there any reason not to create a sysfs directory:

	/sys/bus/usb/devices/usbfs

which would contain symlinks to each USB device, where the name of the 
symlink would be $busnum.$devnum ?  For example:

/sys/bus/usb/devices/usbfs/1.1 -> ../../../../devices/pci0000:00/0000:00:1d.0/usb1/
/sys/bus/usb/devices/usbfs/1.2 -> ../../../../devices/pci0000:00/0000:00:1d.0/usb1/1-2/

This would permit users of usbfs to quickly find the sysfs directory
for a particular device without having to search through a whole bunch 
of device directories and files.

Would it be better to create the usbfs directory one level higher, 
directly under /sys/bus/usb ?

If there's nothing wrong with this, what is the best way to do it?  Use 
a bare kobject for the directory?

Thanks,

Alan Stern
