howto mount usbfs /proc/bus/usb with other group id

I've installed Arch 0.8 (voodoo) and VirtualBox.  I've downloaded the binaries from the Virtualbox website as I need USB support.
The virtualbox manual mentions to check and change usbfs mount options to have a seperate group (e.g. usb) that has access to the USB file system.

I see that /etc/fstab hasn't got any entry mounting usbfs and only place I find is was /etc/rc.sysinit.
However, if I change the mount options and reboot, no change has happened on the permissions ; it remains :

[root@dv9000 ~]# ls -la /proc/bus/usb
total 0
drwxr-xr-x 7 root root 0 2007-02-18 08:58 .
dr-xr-xr-x 5 root root 0 2007-02-18 08:00 ..
dr-xr-xr-x 2 root root 0 2007-02-18 08:58 001
dr-xr-xr-x 2 root root 0 2007-02-18 08:58 002
dr-xr-xr-x 2 root root 0 2007-02-18 08:58 003
dr-xr-xr-x 2 root root 0 2007-02-18 08:58 004
dr-xr-xr-x 2 root root 0 2007-02-18 08:58 005
-r--r--r-- 1 root root 0 2007-02-18 10:11 devices

How and where do I change the usbfs mount settings ?
I want something like this :

[root@dv9000 ~]# ls -la /proc/bus/usb
total 0
drwxr-xr-x 7 root usb 0 2007-02-18 08:58 .
dr-xr-xr-x 5 root usb 0 2007-02-18 08:00 ..
dr-xr-xr-x 2 root usb 0 2007-02-18 08:58 001
dr-xr-xr-x 2 root usb 0 2007-02-18 08:58 002
dr-xr-xr-x 2 root usb 0 2007-02-18 08:58 003
dr-xr-xr-x 2 root usb 0 2007-02-18 08:58 004
dr-xr-xr-x 2 root usb 0 2007-02-18 08:58 005
-r--r--r-- 1 root usb 0 2007-02-18 10:11 devices

I already tried next post, but initscripts seems to be changed in the meantime. I can't find this nousbfs.

Never mind ... I was using wrong syntax to check : ls -lR /proc/bus/usb and not ls -la. 

Adding an entry to /etc/fstab just works fine.

Has something changed, I have tried everything and I cannot get the permissions to change. I have added an entry to fstab, I have added several entries to UDEV rules, I have removed the nousbfs from rc.sysinit and absolutely nothing works.
